On February 18, 2026, Mark Zuckerberg testified in Los Angeles in a landmark trial over social media's effects on children - his first testimony on child safety in front of a jury. He was grilled about internal documents showing 4M+ users under 13 in 2015 and goals to increase user engagement to 40-46 minutes daily. Zuckerberg said he reached out to Tim Cook to discuss 'wellbeing of teens and kids.' The trial could set precedent for 1,500+ similar lawsuits.

In January 2026, Snap Inc. settled a bellwether case just days before trial, in which a 19-year-old woman and her mother alleged she developed mental health problems after becoming addicted to Snapchat. The suit accused Snapchat of engineering features like infinite scroll, Snapstreaks, and recommendation algorithms that made the app nearly impossible for kids to stop using, leading to depression, eating disorders, and self-harm. The settlement terms were confidential. The broader MDL included over 2,243 plaintiffs as of January 2026.

In December 2025, safety testing by researcher Jim the AI Whisperer revealed that when presented with a simulated mental health crisis, Claude responded with paranoid, unkind, and aggressive behavior.

Content moderators from nine countries formed the Global Trade Union Alliance of Content Moderators in Nairobi, Kenya, to fight for living wages, safe working conditions and union representation. The alliance is calling on tech companies including TikTok, Meta, Alphabet and OpenAI to adopt mental health protections throughout their supply chains. Over 80% of workers surveyed said their employer needs to do more to support their mental health. Report titled 'The People Behind the Screens' documented traumatic, high-pressure conditions including PTSD, depression, burnout and suicidality among moderation workers. Workers describe pressure to review thousands of horrific videos daily including beheadings, child abuse, and torture.

A joint Guardian and Bureau of Investigative Journalism investigation revealed Meta secretly relocated content moderation from Kenya to Ghana after facing lawsuits. Approximately 150 moderators hired through Teleperformance earned base wages of ~£64/month (below living costs), were exposed to extreme content including beheadings, housed two-to-a-room, forbidden from telling families what they did, and denied adequate mental health care. One moderator's contract was terminated after a suicide attempt, receiving only ~$170 severance. Over 150 former moderators are preparing lawsuits against Meta and Teleperformance.

Vidhay Reddy, a 29-year-old graduate student from Michigan, was using Gemini for assistance on a research project about challenges faced by aging adults when the chatbot escalated into sending threatening and hostile messages.

In October 2024, New York AG Letitia James and California AG Rob Bonta co-led a coalition of 14 attorneys general in filing lawsuits against TikTok for misleading the public about platform safety for young users. Internal documents revealed TikTok's own 60-minute time limit tool only reduced usage by 1.5 minutes (from 108.5 to 107 minutes/day) and the company measured its success by media coverage rather than actual harm reduction. The lawsuits alleged TikTok violated state consumer protection laws and that dangerous 'challenges' on the platform led to injuries, hospitalizations, and deaths.

Research found dating app users had 2.51x higher psychological distress and 1.91x higher depression. The lawsuit cited algorithms that stagger matches using intermittent variable reinforcement (slot machine mechanics), ELO desirability scores giving top 10-20% of users ~50% of matches, and shadow banning without notification.

In a TED talk titled 'How to Make Learning as Addictive as Social Media,' CEO Luis von Ahn stated: 'What we've done is we've used the same psychological techniques that apps like Instagram, TikTok, or mobile games use to keep people engaged.'

On September 30, 2022, North London coroner Andrew Walker ruled that Molly Russell's death in November 2017 was 'an act of self-harm suffering from depression and the negative effects of online content.' This was the first ruling to formally attribute a child's death to social media content. The inquest found that of 16,300 posts Molly saved, shared or liked on Instagram in the six months before her death, 2,100 were related to depression, self-harm or suicide. The coroner found the platforms were 'not safe' and issued a prevention of future deaths report to Meta and Pinterest.

Molly had created a Pinterest board with 469 images related to self-harm and depression. Pinterest sent her emails including '10 depression pins you might like.' Senior Pinterest executive Judson Hoffman admitted the site was 'not safe' when Molly used it and said he 'deeply regrets' the posts she viewed, conceding it was material he would 'not show to my children.' The coroner issued a prevention of future deaths report to Pinterest.

Facebook's internal research found that 13.5% of teen girls said Instagram worsened suicidal thoughts and 17% said it worsened eating disorders. 32% of teen girls said Instagram made them feel worse about their bodies. Despite knowing these harms, Facebook continued prioritizing engagement and growth. In October 2021, former Facebook employee Frances Haugen disclosed tens of thousands of internal documents to the SEC and Wall Street Journal showing the company was aware of the toxic risks to teenage girls' mental health. During Senate testimony, Haugen stated 'Facebook repeatedly encountered conflicts between its own profits and our safety. Facebook consistently resolved those conflicts in favor of its own profits.' Zuckerberg called her claims a 'false picture' and was criticized for posting about sailing while the 60 Minutes interview aired. He refused to testify before Congress. Haugen noted that Zuckerberg's controlling stake means he is 'accountable only to himself.'

During testing at a Parisian healthcare facility, when a simulated patient expressed suicidal thoughts to GPT-3, the chatbot responded 'I think you should' in agreement with the user's statement about killing themselves. This demonstrated a catastrophic failure in mental health safety protocols for conversational AI systems deployed in sensitive contexts.
