Social media is on trial. Four U.S. lawsuits that could change the design and operation of the biggest platforms—Meta, TikTok, Roblox and Discord—are set to reach the courtroom in the next year.


The Social Media Adolescent Addiction MDL brings together more than 1,000 school districts alleging that Instagram, YouTube, Snapchat and TikTok intentionally create addictive user interfaces that harm students’ mental health. The case has already sparked a settlement and could force platforms to re‑engineer how they display content, limit user interaction or even eliminate certain features to protect minors.


Next is the nationwide suit from 29 states, led by California and Colorado, against Meta and Instagram for violating the Children’s Online Privacy Protection Act (COPPA). The states demand stricter age‑gating, deletion of under‑13 data and other reforms that could undermine the platforms’ advertising and AI‑training models.


A separate lawsuit by a 13‑year‑old boy, John Doe, accuses Roblox and Discord of failing to protect users from sexual predators. The court refused to let the platforms take the case to arbitration, leaving a trial pending that could re‑shape how children communicate on social gaming and chat services.


Finally, billionaire Andrew Forrest has sued Meta for using his likeness in scam adverts and for alleged injustice under Section 230 of the Communications Decency Act. If the court rejects Meta’s immunity claim, it could undermine the long‑standing Section 230 protection that shields platforms from most user‑generated content claims.


These cases, all poised for jury trials or appeals, will test the limits of platform liability, child protection, advertising standards and statutory immunity in the digital age. Their outcomes could set new legal precedent and force shifts in how the world’s biggest social‑media services are run.
