A wave of civil litigation is sweeping across Europe as families accuse social media giants of contributing to child suicide and self-harm through addictive algorithms. These cases mirror recent United States rulings, where courts have begun holding platforms financially accountable for negligence regarding youth safety.

In Italy, a landmark class action lawsuit against TikTok and Meta seeks mandatory age verification and algorithmic transparency. Plaintiffs aim to protect an estimated 3.5 million Italian children under 14 who are illegally active on these platforms. Defense attorneys have challenged the court's jurisdiction and disputed scientific evidence linking platform design to psychological harm.

French authorities have escalated their response beyond civil suits. Prosecutors opened a formal criminal investigation into TikTok regarding the alleged promotion of suicide-related content and unlawful data collection. The advocacy group Algos Victima has expanded its lawsuit to represent sixteen families, citing specific instances where algorithms allegedly exposed teenagers to material promoting eating disorders and self-harm.

Litigation has also reached the United Kingdom. The family of Murray Dowey, a Scottish teenager who died by suicide after being exploited on Instagram, joined a wrongful death suit against Meta. Advocates allege the company knowingly maintained design features that allowed adult strangers to message minors, rejecting internal recommendations to default teen accounts to private settings.

This European legal surge follows a significant precedent set in California. A judge recently denied requests from Meta and Google for a new trial in an addiction case, upholding a six million dollar verdict. Courts on both sides of the Atlantic are now scrutinizing whether tech companies deliberately prioritized engagement over child welfare.
