Arturo Bejar in Meta Trial: Ex-Engineer Says 14-Year-Old Daughter Was ‘Prey’ on Instagram, Got S*x Requests

Arturo Bejar, a former Facebook safety engineer and Instagram consultant, spent six years working on child safety tools at Meta Platforms Inc.'s Facebook, but told a jury he did not fully understand the threats posed to young users on the platform until his 14-year-old daughter signed up for an Instagram account.

"She started getting requests for s*x and pictures of private parts from people that she did not know," Bejar said. "I found it shocking."

Historic Trial Puts Meta's Youth Safety Practices Under Scrutiny

Bejar testified about his experience during the first day of a historic trial in California, in which a coalition of state attorneys general have accused Meta of deliberately designing Facebook and Instagram to encourage compulsive use among youths and collecting data from users under 13 years old, in violation of federal law. Meta Denies Allegations That Instagram and Facebook Are Designed to Addict Teens.

The stakes at the trial are high. If the company loses, it may face financial penalties ranging from USD 193 billion to USD 1.4 trillion, and court orders that could force changes in how it operates its platforms, reports said.

Meta has denied wrongdoing, saying it has continuously improved tools to protect kids and calling the states' proposed penalties "outlandish."

'Significant Harms' Known But Unaddressed, Says Bejar

During his time working on safety research at the company, Bejar said, executives were well aware of "significant harms" to young people on its platforms but they repeatedly failed to make changes or introduce features that would have a measurable impact. Why Was Meta Ordered To Pay USD 567 Million?

"Young people, in particular, were experiencing harm at high rates and they weren't getting the attention, investigation, support or remediation that they needed," Bejar testified Tuesday.

Bejar started working for Facebook in 2009 as a manager overseeing safety, but he said he left in 2015 to take care of his teenage children. In 2019, after his daughter's experience on Instagram, he returned to Meta as an independent contractor working on the platform's "well-being" team.

Meta Attorney Presses Bejar On His Own Role

On Wednesday, Brian Stekloff, an attorney for Meta, pressed Bejar on his initial role at the company, suggesting that he would have been well-positioned to address the safety issues he was testifying about while he was working at the company.

"You weren't able to solve every safety issue, correct?" Stekloff said.

"Harm is not a mathematical equation that you solve to get to zero," Bejar said.

He left Meta for good in 2021, the same year that Frances Haugen, a former product manager-turned-whistleblower at Facebook, revealed internal documents showing that Meta had long known that its platforms had ill effects on young people, especially girls struggling with their body image.

A Go-To Whistleblower In Meta Litigation

Bejar testified before Congress in 2023 about his concerns and has since emerged as a go-to whistleblower witness for states and personal injury attorneys suing Meta and other social media platforms on similar grounds. He took the stand in the previous two trials against Meta in Los Angeles and New Mexico, both of which ended with verdicts against Meta. Bejar also testified in an ongoing trial against Meta in Tennessee, where he was on the witness stand for four days.

In the current case in federal court in Oakland, California, Meta fought to bar Bejar from testifying, arguing that he violated evidence rules by using auto-deleting messaging apps to communicate with former Meta employees about the case. US District Judge Yvonne Gonzalez Rogers on the eve of trial denied Meta's last-minute motion and allowed him to take the stand.

Stekloff Questions Bejar Over His Own Daughter's Account

During Wednesday's cross examination, Stekloff questioned Bejar about his daughter's social media activity. The attorney noted that during the father's time as a consultant for Meta, his daughter at age 16 created a public Instagram account where she posted about her passion for cars.

"Knowing everything that you talked about at length yesterday and this morning, understanding the good and the bad, you consciously allowed her to open this account?" Stekloff said.

Bejar said he and his daughter dealt with instances of abuse on her public page as they arose.

"My job as a parent was to support her to deal with that," he said. "This is an issue that we discuss frequently and she understands the nature of harm and what the company could do better about it."

Zuckerberg, Mosseri Expected To Testify

The trial in Oakland is focused on alleged violations of state consumer protection and federal privacy laws, and is being led by attorneys general from California, Colorado, Kentucky and New Jersey.

A lawyer for the states told jurors Tuesday that besides Bejar, they would hear during the trial from half a dozen other ex-Meta employees, as well as from Meta Chief Executive Officer Mark Zuckerberg and Instagram head Adam Mosseri.

The case is People of the State of California v. Meta Platforms Inc., 23-cv-05448, US District Court, Northern District of California (Oakland).
