France Opened a Criminal Investigation Into How TikTok's Algorithm Fed Suicide Content to Teenagers

What happened

French prosecutors opened a criminal investigation into TikTok in November 2025 after multiple families and a parliamentary process accused the platform's recommendation algorithm of steering vulnerable teenagers toward content glorifying self-harm and suicide. The investigation was not about a single piece of harmful content escaping moderation. It was about whether the algorithm itself functions as a delivery mechanism for harm.

Several French families and a parliamentary committee filed legal and criminal complaints against the company, citing cases in which teenagers as young as 13 were directed by TikTok's For You feed into content promoting self-harm, eating disorders, and suicide. Two of the adolescents at the center of the complaints, both 15 years old, died by suicide. Prosecutors are examining whether TikTok violated French law against promoting suicide methods and whether it failed a legal obligation to alert authorities when dangerous content appeared on its platform.

Research by Amnesty International documented the mechanism in detail. In tests using newly created accounts, the platform began surfacing depressive content within minutes of a user showing interest in sad material. The proportion of that content more than doubled as the account aged, and some videos included explicit descriptions of suicide methods. Amnesty concluded that TikTok's design amplified risk rather than mitigated it: the more a young user engaged with difficult material, the more the system supplied.

TikTok denied the allegations and stated it operates more than 50 safety features designed to protect teenagers and removes 90 percent of policy-violating videos before they are viewed by anyone. The company did not directly address the Amnesty findings. The investigation arrives as the European Union is already applying pressure on major platforms under the Digital Services Act, which requires companies to assess and reduce systemic risks from their recommendation systems, including risks to young users' mental health.

The core question the investigation is trying to answer is not simply whether harmful content appeared on the platform. It is whether the recommendation system was built or operated in a way that made harmful content more likely to reach the users least equipped to handle it, and whether TikTok can demonstrate otherwise. Without a provable record of what the system did, which signals it amplified, which safety features were active, and for which users, that question cannot be resolved in court any more than it can be resolved in a press statement. That accountability gap is structural, and the families who lost children to it are now asking a criminal court to close it.
