An Italian mother has joined a landmark lawsuit against Meta and TikTok after the death of her 12-year-old daughter, Rossella, who died by suicide in 2024. Her parents say they discovered after her death that she had been heavily exposed to self-harm and depressive content on social media, including through a secret Instagram account. They allege that platform algorithms repeatedly promoted harmful material that worsened her mental state.

The case, the first collective legal action of its kind in Italy, seeks stronger protections for minors online and greater accountability from social media companies. Several families argue that current safeguards are insufficient and that algorithms are designed to encourage prolonged engagement, potentially exposing vulnerable children to harmful content. Meta and TikTok deny the allegations, stating that they actively remove dangerous material and have introduced tools to protect young users.

The lawsuit comes amid growing scrutiny of social media platforms across Europe and beyond. Regulators are increasing pressure on technology companies to strengthen child safety measures, while experts continue to debate the long-term impact of social media on adolescent mental health. Rossella’s mother says she joined the case to raise awareness and help other families recognize risks before it is too late.
