A whistleblower has testified that Meta, the parent company of Facebook and Instagram, ran a safety trial that deliberately ignored warnings about child sexual exploitation and grooming on its platforms. The testimony, delivered to a US Senate committee on 19 August 2026, alleges that senior executives at the company were aware of the failures but chose not to act.
Whistleblower details safety trial failures
The whistleblower, a former Meta employee who worked on the company’s safety team, told the Senate Judiciary Committee that a trial designed to test new safety features for minors was fundamentally flawed. According to the testimony, the trial was set up in a way that excluded the most high-risk accounts, including those already flagged for suspicious behaviour involving children.
“The trial was structured to produce a positive result, not to protect children,” the whistleblower said, according to a transcript of the hearing. “When we raised concerns internally, we were told to focus on the metrics that would make the trial look successful.”
Internal warnings ignored
The whistleblower further testified that internal reports from Meta’s own safety analysts showed a significant increase in reports of child sexual exploitation material (CSEM) and grooming attempts during the trial period. Despite this, the company did not halt the trial or modify its parameters. Instead, the whistleblower alleged, Meta publicly touted the trial as a success in blog posts and investor communications.
“We had data showing that the number of grooming reports had risen by 23% in the trial group compared to the control group,” the testimony stated. “But the company’s public statements claimed the opposite.”
Meta’s response and ongoing scrutiny
Meta has denied the allegations. In a statement issued after the hearing, a company spokesperson said: “Meta takes child safety extremely seriously. The trial in question was carefully designed with input from external experts and was reviewed by our internal ethics board. We strongly dispute the characterisation of events presented in today’s testimony.”
The Senate committee has launched a formal investigation into Meta’s safety practices, with further hearings expected in the coming months. The whistleblower’s testimony has also prompted renewed calls from child safety advocates for stronger regulation of social media platforms, including mandatory independent audits of safety features.
“This is not just about one trial,” the whistleblower concluded. “It’s about a culture at Meta that consistently puts engagement and profit above the safety of children. Until that changes, no amount of feature trials will make a difference.”
