EU regulators formally charged TikTok on Friday with violating the Digital Services Act over its algorithm's "rabbit hole" effects, putting ByteDance at risk of a fine of up to 6% of its global annual revenue.
European Union regulators formally charged TikTok on Friday with breaching the bloc's online content rules, citing the harmful "rabbit hole" effects produced by the platform's recommendation algorithm — a designation that puts parent company ByteDance at risk of a fine worth up to 6% of its global annual turnover.
The European Commission, which serves as the EU's principal tech regulator, issued what it calls preliminary findings to TikTok after concluding that the company had failed to put proportionate, reasonable, and effective measures in place to address systemic risks posed by its recommendation engine.
At the core of the charges is TikTok's "For You" feed, which regulators say serves users an uninterrupted stream of similar content based on their scrolling and liking behavior, drawing them into loops they cannot easily exit.
"Every time a user scrolls or likes a video on TikTok, the algorithm serves more of the same leading users down rabbit holes they cannot easily escape from," EU tech chief Henna Virkkunen said in a statement. "Today's preliminary findings show again that TikTok needs to step up its efforts to protect users' well-being, including those of minors," she added.
The Commission specified that prolonged exposure to content centered on sadness, isolation, or body image can produce detrimental effects on users' mental health, with minors named as a particularly vulnerable group.
Among the corrective measures regulators outlined, the Commission said TikTok must redesign its "For You" feed to rely more heavily on users' explicitly stated preferences, expand the accessibility and usability of user controls, and conduct regular algorithmic testing.
ByteDance has until next year to resolve the issues or face the potential fine. The company has previously contested EU findings on related matters. When charged in February over addictive design features, insufficient child protections, and restricted researcher access to public data, TikTok said those preliminary findings were "categorically false" and vowed to challenge them.
Friday's charges fall under the EU's Digital Services Act, which obligates large online platforms to do more to identify and mitigate harmful or illegal content on their services. The act carries meaningful financial penalties, giving the Commission leverage it has increasingly used against major platforms.
The latest action is part of a broader regulatory push. The Commission is separately investigating Facebook and Instagram, both operated by Meta Platforms, over similar concerns about rabbit hole effects driven by their own recommendation systems.
The global pressure on social media companies over algorithmic harm to children has intensified across jurisdictions in recent years, with several governments either imposing or weighing outright bans on platform access for underage users. TikTok, with its youth-heavy user base and Chinese ownership, has remained at the center of that scrutiny.
Whether ByteDance can satisfy regulators before a formal penalty decision is reached will likely depend on the depth and speed of the algorithm redesign it is willing to undertake — a process that carries its own commercial risks, given that engagement-driving recommendation systems sit at the heart of TikTok's business model.
