Peiter ‘Mudge’ Zatko on Why He Blew the Whistle on Twitter

Peiter Zatko, the Twitter whistle-blower, is a black belt in jiu-jitsu. The day earlier than his grievance towards the social media firm was revealed, Zatko was sitting in his lawyer’s workplace in Washington, scrolling by means of his digicam roll to discover a picture of his legs locked round somebody’s neck. The transfer known as a side-triangle. It’s completely secure, he says, as a result of the opponent will black out earlier than a scarcity of blood movement to the mind could cause any lasting injury. One of many issues Zatko likes in regards to the martial artwork, he explains, is that it’s much less about brute power than discovering inventive methods to maneuver your opponent right into a weaker place.

That expertise interprets to cybersecurity. In Nov. 2020, Zatko, the hacker generally known as “Mudge,” was employed as Twitter’s safety lead, with a world remit to repair gaping vulnerabilities in one of many world’s most essential communications platforms. However 14 months later, he was fired. Six months after that, he filed a sweeping whistle-blower grievance that paints a damning portrait of an organization in disaster. In an 84-page grievance to federal regulatory businesses and the Division of Justice, which was first reported by the Washington Publish and CNN and which TIME obtained from a congressional supply, he describes Twitter as crippled by rudderless and dishonest management, beset by “egregious” privateness and safety flaws, tainted by international affect, a hazard to nationwide safety, and prone even to complete collapse.

Zatko says he felt an moral obligation to return ahead. “Being a public whistle-blower is the final resort, one thing that I might solely ever do after I had exhausted all different means,” he informed TIME in a prolonged interview on Aug. 22. “It isn’t a straightforward path, however I view it as persevering with to assist enhance the place the place I used to be employed.”

Twitter rapidly hit again. Zatko was fired for “ineffective management and poor efficiency,” CEO Parag Agrawal wrote in an electronic mail to workers, calling the disclosures a “false narrative that’s riddled with inconsistencies and inaccuracies” and offered out of context. “Mudge was accountable for a lot of points of this work that he’s now inaccurately portraying greater than six months after his termination,” Agrawal stated.

The story of how a high Twitter official turned whistle-blower will not be a simple saga. In additional than a dozen interviews with Zatko’s mates, household, and present and former colleagues, the portrait that emerges is extra difficult. Eight present and former Twitter workers, who spoke with TIME on situation of anonymity so as to talk about points they weren’t licensed to talk publicly about, stated that many points of Zatko’s disclosures rang true to their expertise, significantly his allegations of safety deficiencies and shortcomings in firm management. A number of the similar sources, lots of whom professed to love and admire Zatko, steered that varied allegations have been deceptive, overblown, or missing context—partially as a result of Zatko was straying into areas of the corporate into which he had solely fundamental perception.

Zatko’s allegations have emerged at a pivotal second for Twitter, which is locked in a authorized battle over an settlement to promote the corporate to Elon Musk. That makes the accuracy and credibility of Zatko’s claims a multibillion-dollar challenge, and the article of appreciable debate by his former colleagues. “Is Mudge usually appropriate? Sure,” says one present Twitter worker who labored with Zatko. “The place he’s appropriate is that Twitter has completely been negligent in creating the suitable safety infrastructure for an organization that has the extent of affect it has … Is Mudge improper about a number of issues? Additionally sure. I feel there’s lots of bitter grapes.”

Zatko had come from an extended line of jobs the place he had free rein to tear up organizational constructions and prioritize safety above all else. However at Twitter, present and former colleagues say, he discovered himself in a unique setting: navigating tense inner politics at a company bent on boosting income, with out assist from his superiors. Some workers caught up within the tumult perceived Zatko to be a determine employed by then CEO Jack Dorsey for publicity causes, stepping on the toes of certified colleagues with extra institutional data. Technically sensible and morally inflexible, Zatko was an iconoclast moving into a company paperwork. “It’s like asking a physician who’s been educated to do mind surgical procedure to abruptly develop into a podiatrist,” says a former Twitter colleague.

The polarized reactions to Zatko’s disclosures illustrate simply how atypical a tech whistle-blower he’s. Final 12 months, Frances Haugen, a former Fb product supervisor, disclosed tens of 1000’s of pages of inner firm paperwork that exposed an organization prioritizing earnings over person security. However readers didn’t need to take Haugen’s phrase for it; they might learn the phrases of Fb’s personal security groups. Zatko is completely different. As a former senior govt, he had a chicken’s-eye view into Twitter’s decisionmaking, in the end liable for a whole lot of employees in a few of Twitter’s most high-priority work streams. However he didn’t launch the identical breadth of documentation as Haugen; whereas Zatko equipped some reveals to assist his claims, together with inner emails, his partially redacted disclosures rely largely on his personal credibility as one of the crucial celebrated figures in cybersecurity. He’s implicitly asking the general public to belief that his model of occasions is the proper one, and that Twitter is mendacity.

Zatko could lose cash by coming ahead. Half of his compensation at Twitter was in money, however the remaining got here in inventory, says John Tye of the legislation agency Whistleblower Assist, which is representing Zatko. The worth of these shares dropped by about 9% when information of Zatko’s allegations broke. Tye insists Zatko’s motivations are rooted in a want to see the corporate achieve the long run, not his personal monetary self-interest.

The destiny of Twitter’s inventory worth could also be simply the primary of a cascading collection of penalties from Zatko’s disclosures. His competition that Twitter has a much bigger bot drawback than executives admit could forestall them from forcing completion of the Musk deal. Tye says that his consumer prefers Twitter to stay a public firm, for the general public good. “We’ve considerations if the SEC have been to lose jurisdiction if the corporate goes personal, as a result of there’s one much less law-enforcement lever,” Tye says. “That’s an issue for accountability.” Zatko informed TIME he has by no means met Musk and didn’t present any data to him upfront of his disclosures turning into public data.

Zatko’s allegations may ripple out even additional, in Washington and past. On Sept. 13, he’s set to testify in Congress in regards to the allegations, which may spur investigations by the SEC and FTC. That would in flip additional erode public religion in social media firms usually, as they face escalating questions on their affect on politics and society, in addition to world efforts to rein them in. All of which implies the query of what sort of whistle-blower Peiter “Mudge” Zatko is has penalties effectively past Twitter’s future.

In his Twitter profile image, Zatko has flowing, shoulder-length brown hair, with a hoop of sunshine hovering above his head like a halo. But it surely’s been greater than twenty years since he traded this long-haired look—“hacker Jesus,” his spouse Sarah Zatko jokes—for a clean-cut mien befitting a person who’s finished excursions on the highest ranges of presidency. As Zatko sat down for his interview with TIME on the eve of the allegations turning into public, he sported a crisp goatee flecked with grey, wired spectacles, and a lapel pin depicting the brand of his attorneys, Whistleblower Assist.

The profile image is not any accident. Zatko cites his well-known work within the Nineteen Nineties as each the defining period of his life and the grounding for his current morality. “I all the time ask myself: What would the Mudge of the late ‘90s take into consideration what I’m doing now?” he says of his determination to blow the whistle on Twitter. “I wish to make sure that I haven’t misplaced that drive, that my ethics are nonetheless simply as robust, that I’m combating for individuals simply as laborious.”

Zatko is each attuned to and expert at nurturing the mythology surrounding him. When he was a toddler, his father hung over his crib a cell manufactured from circuit boards. “He wished me to not be afraid of expertise,” he stated in a 2011 interview with a commerce journal. He says he started hacking on the age of 5, choosing locks and reverse-engineering pc video games together with his dad on a late-Seventies Apple II pc to get round copyright protections. As a youngster, he spent his time browsing ARPANET, the predecessor to the fashionable web, together with the bulletin boards the place communities of on-line hackers have been taking form.

Rising up in Alabama and Pennsylvania within the Nineteen Eighties, his childhood heroes have been the social activist Abbie Hoffman and the musician Frank Zappa. Zatko studied the guitar and the violin, and selected music over pc science, attending the Berklee School of Music in Boston. After graduating, he break up his time between taking part in at golf equipment together with his progressive metallic band Raymaker, part-time tech-support work, and dealing with a high-profile hacker “suppose tank” referred to as the L0pht (pronounced Loft) to show company safety flaws. He would quickly develop into its most distinguished member and went on to affix a hacking cooperative generally known as the Cult of the Useless Cow.

On the L0pht, Zatko pioneered a technique of publicly embarrassing firms that refused to patch vulnerabilities that he and his fellow hackers had flagged to them. His greatest nemesis within the Nineteen Nineties was Microsoft. When Zatko and his colleagues confirmed it was attainable to insert malicious code to run secretly on any machine, Microsoft ignored it. So the L0pht launched a user-friendly device that allowed anyone to interrupt into Home windows customers’ private accounts, reasoning that it was the one approach to pressure the corporate to lastly repair its vulnerabilities. It labored. As we speak, Zatko says, Microsoft has one of the crucial superior safety applications on this planet.

Nonetheless, “accountable disclosure,” because the tactic of public embarrassment grew to become identified, is a little bit of a misnomer. Criminals may use the hacking program he launched to crack passwords in lower than 24 hours, enabling them to steal credit-card or medical knowledge from harmless customers utilizing unpatched machines. Zatko says that he thought “lengthy and laborious” earlier than deciding that releasing the device was the one approach to make Microsoft change its methods and defend its customers, even when some individuals bought harm within the quick time period.

“Dishonesty is certainly one thing that frustrates him,” says his spouse Sarah, a former mathematician on the Nationwide Safety Company. “It doesn’t imply he’s all the time making an attempt to make a giant public fuss, as a result of if you may get issues mounted … by means of correct channels it’s all the time simpler on everyone. But when that’s not attainable, there’s all the time this fallback.”

Zatko and different members of the L0pht agreed to testify about web safety on Capitol Hill in Could 1998. Within the congressional listening to room, they have been recognized on their placards solely by their hacker names. Zatko sat within the middle of the group of seven hackers and did many of the speaking. Even then, he flashed a aptitude for the dramatic, getting lawmakers’ consideration by infamously claiming he may take down the web in half-hour. “How can we be anticipated to guard the system and the community,” Zatko requested the assembled Senators, “when all the seven people seated earlier than you’ll be able to tear down the muse that the community was constructed upon?”

Nonetheless in his 20s, he started to work as an unofficial adviser on internet-security points to Richard Clarke, who would develop into the cybersecurity czar for 3 completely different U.S. Presidents. A photograph from 2000 reveals Zatko on the first White Home assembly on cybersecurity, speaking to then President Invoice Clinton.

After the terrorist assaults of Sept. 11, 2001, cybersecurity abruptly grew to become an pressing a part of counterterrorism technique. Unhealthy actors and “spam gangs” run out of Russia and Japanese Europe have been releasing viruses and different malware, wreaking havoc on techniques unprepared to counter them. Zatko started advising U.S. intelligence businesses and the army without cost.

Zatko was shaken by what he uncovered when he began digging. “I began to determine quite a few methods of knocking the monetary sector down,” he says. “It simply began to daybreak on me that I, as a person actor, may wreak severe havoc. And that is shortly after 9/11.” He had a nasty response to medication that his psychiatrist prescribed to cope with his rising nervousness, which solely made issues worse. It took a very long time for him to emotionally recuperate. “Each safety skilled has the second the place they’ve began to study sufficient in regards to the subject that abruptly they’ve this existential disaster,” says Zatko’s spouse Sarah. “Then you definately both develop into [nihilistic] and every little thing’s hopeless, or else you must determine a approach to get previous it and attempt to repair your nook of issues.”

Out of his rut and adopting that new mindset, Zatko was tapped in 2010 to guide cybersecurity efforts on the Protection Superior Analysis Initiatives Company (DARPA). “I didn’t go there as a result of I assumed it was cool. I didn’t go there as a result of I wished to be part of the federal government,” he informed the viewers on the DEF CON hacker convention in 2013. “I really went there as a result of I assumed they and different components of presidency had form of misplaced their method, and I had a chance to go in and repair it.”

One among his first strikes was bringing in hackers and forcing profession officers on the army workplace to spend three days in a convention room with them, says Renee Rush, a U.S. Air Power veteran who labored with him on the company. “Mudge may go anyplace and get a giant paycheck,” Rush says, “however you’ll by no means discover him in a job that doesn’t have a particular mission.”

Zatko’s sense of precept has a method of engendering loyalty amongst his many mentees, each inside and out of doors his subject. Ryan Corridor, a champion blended martial artist, grew to become shut mates with Zatko after Zatko joined Corridor’s gymnasium in Arlington, Va., in 2010 to follow jiu-jitsu. He remembers seeing Zatko at a espresso store a block from the gymnasium, sporting denims and a T-shirt, surrounded by males in well-cut fits. “Peiter has little or no time for ethical waffling,” Corridor says.

After 3½ years, Zatko left DARPA for stints doing safety analysis at Google and the fee processor Stripe. He forged each as firms that took safety recommendation severely. “The executives really again safety and allow us to do issues otherwise (in any other case I wouldn’t be there!),” he tweeted approvingly in 2018 whereas at Stripe.

Over time, web safety has grown extra difficult as its affect expands past scams, cyberattacks, and company or authorities safety hacks. Zatko publicly expressed his frustration that veteran safety consultants’ recommendation was being ignored within the lead-up to the 2016 election. The Democratic Nationwide Committee reached out to him for assist to enhance its community and knowledge safety, however even his most simple solutions have been thought-about too “annoying,” he stated. “DNC creates Cybersecurity board made up of well-meaning individuals with no cybersecurity experience,” he tweeted in August 2016. “Your transfer Russia…”

4 years later, after the Trump period confirmed simply how important the safety of social media platforms was for safeguarding democracy, Zatko was sitting in his house workplace in New Jersey. The room is in an extension with no central heating or cooling system. Within the winter, it’s warmed by “method too many” pc cores—over 100, he estimates. It’s a messy area, with dog-eared textbooks strewn throughout the ground and framed letters of reward from nationwide safety luminaries on the partitions. Zatko’s cellphone rang. On the opposite finish was Dorsey. The person who had co-founded Twitter addressed him as Mudge, and informed Zatko the hacker’s work through the Nineteen Nineties was one of many causes he pursued a tech profession. “That simply blew my thoughts,” Zatko remembers. “I’m speaking to the man who created, let’s face it, a platform that’s essential worldwide. It influences governments, social change, it’s the notion many individuals have of the world. And he was telling me that he was curious about me.”

Zatko ultimately determined to simply accept the unorthodox job Dorsey was providing, overseeing Twitter’s total safety operations, each knowledge and bodily. Zatko noticed the safety of a platform as influential as Twitter as maybe his only approach to “make a dent within the universe”—a private motto originating from his time on the L0pht.

The transfer was hailed by consultants as an indication of Twitter’s severe dedication to fixing long-standing safety points. As one safety analyst put it, “A uncommon second of cybersecurity sunshine the place it appears the precise particular person is put within the lead on addressing a significant challenge.”

Twitter wanted him. The corporate was reeling from one of the crucial embarrassing incidents in its 16-year historical past. In July 2020, a trio that included two youngsters used extraordinarily fundamental phishing strategies to realize entry to the accounts of Twitter workers. They have been then in a position to ship tweets from the accounts of Joe Biden, Barack Obama, Elon Musk, and a slew of different blue-checked accounts, establishing a rip-off that netted them over $100,000 in Bitcoin.

The incident was hardly the corporate’s first main safety lapse. The 12 months earlier than, the U.S. authorities had accused two Twitter workers of being moles for the Saudi Arabian authorities. This month, one among them was discovered responsible in federal court docket. Again in 2011, the FTC had filed a grievance towards Twitter for failing to guard client data. That grievance was purported to end in Twitter implementing a strong safety program proof against cyberattacks. But the success of the July 2020 hackers confirmed how susceptible the platform remained. “Whereas Google, Microsoft, Apple, and Meta constantly put out new options to assist individuals defend their accounts and knowledge, Twitter’s focus appeared to be a bit stale,” says Runa Sandvik, a privateness and safety researcher. “It’s unclear what Twitter was doing in that area, if something in any respect.”

Zatko’s whistle-blower grievance says he anticipated to spend the rest of his profession working at Twitter. But it surely rapidly grew to become obvious that the corporate was “a decade behind” its rivals, he wrote in a employees memo included within the disclosures. Groups combating bots have been understaffed and overworked, he alleges, and inner safety measures Twitter promised to develop within the wake of the 2011 FTC mandate had but to be rolled out. Zatko’s grievance claims {that a} severe safety breach was occurring at Twitter on common each week.

On Jan. 6, 2021, Zatko was watching the Capitol rebellion unfold on-line and requested a Twitter engineering govt to curtail workers’ entry to inner techniques. He discovered that too many workers had irrevocable entry. One rogue engineer with the precise system privileges may have sabotaged the platform, sowing misinformation and discord, Zatko alleges in his disclosure.

Zatko tried to patch these holes. He shuttered a number of present safety and privateness applications in favor of a brand new division, optimistically named Confidence. He drew up a three-year plan to enhance protection efforts and measure spam bots, which he alleges have been operating rampant and unchecked throughout the platform. In line with his disclosure, he was met with continuous pushback at senior ranges of the corporate, and when it got here to safety points, he says, “deliberate ignorance” was the norm. Some product managers have been “inspired” to override safety and privateness points so as to launch new merchandise extra rapidly, his grievance alleges. Present and former Twitter workers who spoke with TIME corroborated the overall sweep of Zatko’s allegations that Twitter typically prioritized revenue over safety. “Except you may make a compelling trade-off argument for why improved safety or privateness will profit the enterprise greater than their price,” says one former Twitter worker, “it’s very laborious to implement change.”

Zatko’s grievance provides that his efforts to tell Twitter’s board about varied safety points have been met with alarm or anger, and that at the least twice he was requested by executives to withhold data from the board. Twitter declined a number of requests from TIME to deal with particular components of Zatko’s allegations. In his electronic mail dated Aug. 23, Agrawal stated Zatko’s disclosures as a complete had many inaccuracies in them. In the meantime, Dorsey, the person who Zatko thought could be his primary ally, was more and more absent and unfocused, Zatko’s disclosure says. A consultant for Dorsey’s firm, Block, didn’t reply to a request for remark for this story.

The scenario started to return to a head in November 2021, when Dorsey resigned. His substitute was Agrawal, who had previously been essentially the most senior govt answerable for safety points earlier than Zatko arrived. Tensions between the 2 rapidly escalated. Zatko says in his disclosures that he grew to become involved that Agrawal was going to make use of the primary board assembly of his tenure to decrease the severity of safety points. He wrote to Agrawal on Dec. 15, arguing that there have been “quite a few, and a few important, misrepresentations” in supplies for an upcoming presentation, in line with emails contained within the grievance.

Agrawal brushed him off, Zatko’s grievance alleges, and the following day, the paperwork have been offered at a high-level Threat Committee board assembly. In a Jan. 4, 2022, electronic mail to Agrawal, Zatko referred to as the paperwork “at worst fraudulent,” and wrote, “I used to be employed to realize sure targets and to repair issues right here at Twitter. As a way to do this, we have to acknowledge the precise state of affairs on the firm.”

A number of days later, Agrawal wrote again to Zatko, saying that the corporate had launched an inner investigation into Zatko’s allegations of “fraud.” Zatko was requested for an in depth report back to again up his claims, which he started to drag collectively. Lower than two weeks later, earlier than he was in a position to file the report, he was fired.

Zatko retained Whistleblower Assist on March 17, a month earlier than Musk provided to purchase Twitter. He concluded he had no alternative however to blow the whistle. “Change generally requires, you recognize, kicking the hornet’s nest slightly bit,” he says. “Ethically and morally, I needed to pursue this.”

In interviews, present and former Twitter officers had differing views on Zatko’s allegations. A number of stated that Zatko was proper about many issues, together with data-management points, chaotic management, and platform vulnerabilities. However some felt he mischaracterized or exaggerated sure particulars within the disclosure, significantly when it got here to points that he himself didn’t work on. “He didn’t know what was occurring with the bots stuff,” says a present worker who labored with Zatko. “That didn’t fall below his safety purview.” Zatko’s attorneys dispute this, arguing that he did in actual fact have perception into and authority over the bots challenge as the last word supervisor of Twitter Providers, which oversees world content material moderation at scale. The disagreement could be chalked as much as Twitter’s messy organizational construction, by which completely different arms of the corporate have competing claims to possession of the bots challenge.

Different components of Zatko’s disclosures merely pit his phrase towards Twitter’s. One among his most explosive claims is that Twitter “knowingly” employed “brokers” of the Indian authorities. Due to entry privileges afforded to many Twitter workers, Zatko says in his disclosure, these alleged brokers may entry delicate person knowledge. The hires got here at a time when the Indian authorities was bristling at Twitter’s refusal to determine particulars about individuals utilizing the platform to criticize the nation’s ruling celebration. Zatko had direct duty for the bodily safety of workers at Twitter, and would doubtless have been immediately briefed on alleged espionage efforts. The disclosures state that Zatko has given extra particulars about this incident to the Division of Justice and the Senate Choose Committee on Intelligence.

Twitter declined a number of requests from TIME to deal with Zatko’s claims about Indian brokers on the file. One particular person with direct data of Twitter’s inner affairs in India informed TIME they’d no data of the supposed agent, however stated they might not be stunned if the Indian authorities had at the least tried to covertly appoint an agent to Twitter’s payroll, much like the Saudi case.

A few of Zatko’s different claims strike consultants as overstated. His disclosure argues that Twitter’s failure to personal the rights to coaching knowledge of machine-learning fashions constitutes “fraud,” for instance. That shortcoming is an industry-wide follow, in line with two former Twitter workers and others acquainted with {industry} requirements.

Because the pushback mounts, Zatko tells TIME he stands by his allegations and for authorized causes is unable to speak about his time at Twitter past what’s within the disclosures. “I used to be conscious of the most typical techniques that may occur, that there could be makes an attempt to character assassinate me or make issues private—something that may distract from the information and the issue at hand,” Zatko says.

Whereas Zatko describes his determination to go public in idealistic phrases, the timing of the disclosures is notable. The trial to resolve whether or not Musk should undergo together with his preliminary settlement to purchase Twitter is about to start out in Delaware on Oct. 17. Zatko inserts himself into this battle from the opening pages of his disclosure, claiming that Twitter is “mendacity about bots to Elon Musk.” Zatko could also be drawn immediately into the court docket case: Musk’s lawyer, Alex Spiro, tells TIME his crew has subpoenaed Zatko, though Zatko’s attorneys say he has acquired no such subpoena.

Two authorized consultants say they’re skeptical Zatko’s claims could have a significant affect on the lawsuit. He offers scant new details about spam bots, and what he does declare about them has little to do with the merger settlement. Ann Lipton, a legislation professor at Tulane College, says that Zatko’s claims that Twitter lied in its SEC filings will likely be laborious to show. “When a disgruntled worker disagrees with administration choices,” Lipton says, “that’s continuously not taken as a ample foundation for treating an SEC submitting as false.”

“The query in the end boils right down to the credibility of the assertions made by the whistle-blower, and that’s normally decided by the existence of laborious proof,” says Howard Fischer, a former SEC legal professional. “Twitter’s actual regulatory danger lies in whether or not or not the documentary proof, and never the doubtless self-serving statements of a former worker, reveals realizing or reckless deceptive of regulators or buyers in public filings and statements.”

The disclosures may produce other long-lasting monetary and political ramifications. The corporate’s inventory worth dropped by round 9% within the wake of the disclosures’ publication. The identical day, Democratic Senator Dick Durbin and Democratic Consultant Frank Pallone introduced they have been investigating Zatko’s claims, with Pallone calling for “the necessity to move complete privateness laws.”

Zatko’s allegations have demoralized Twitter workers, some present staffers say, and will exacerbate a mind drain at an organization that has misplaced lots of its leaders and considerably slowed its spending whereas in Musk-induced limbo. Twitter nonetheless has a major affect on elections and political discourse all over the world, and people who are nonetheless engaged on its safety and privateness groups will “need to work three or 4 occasions tougher,” says a former Twitter worker.

Understanding that his actions would trigger company chaos and catalyze authorities investigations, Zatko says he made his determination with one objective in thoughts: to make Twitter, and thus the world, safer. Though proper now the general public can solely take him at his phrase, that won’t maintain true for lengthy. When he testifies earlier than Congress in September, Zatko—who refused to debate the meat of his grievance in his interview with TIME—could have the authorized cowl to increase on the allegations, probably revealing new and damaging particulars about what occurred inside Twitter.

Zatko will not be the youthful star hacker he was once. Two days earlier than his interview with TIME, he broke a toe whereas sparring with a jiu-jitsu opponent, an accident he chalks up partially to partial paralysis of his again, which he says his physician informed him has been introduced on by the stress of the previous few months. Damage, nonetheless, could also be crucial in the event you’re going to have interaction within the battle. “In case you’re simply reacting to what an adversary is doing, they’re those which can be shifting you round and manipulating you,” he says. “That’s all too frequent on this {industry}.”
