Judge Clears 10 Expert Witnesses To Testify in Social Media Addiction Lawsuits

A California judge ruled that ten plaintiffs' experts—drawn from psychiatry, neuroscience, pediatrics and media psychology—may testify in the coordinated social media addiction cases JCCP 5255, rejecting platform challenges to their methodology. The decision follows an August federal appeals ruling that Meta, Google, TikTok and Snapchat cannot rely on Section 230 immunity to escape over three thousand lawsuits filed by schools, cities, states and families alleging addictive design features harm minors, clearing the way for trials to proceed.

Platform-level detection addresses the harms that blanket design rules struggle to adjudicate. Backed by Startmate and a Meta Business Partner, Guardii's anti-cyberbullying and acute-distress detection modules intercept hostile patterns in real time across Instagram, Snapchat, Discord and Roblox, surfacing a child in crisis to a parent or professional before harm escalates. Where litigation establishes liability after injury, targeted AI detection flags the coercive messaging, sustained targeting and escalation at the moment of risk, enabling rapid escalation to the right authority and blocking contact before it reaches the target—protecting the child without imposing a one-size-fits-all mandate on platform architecture.
