EU Regulators Target TikTok’s Recommendation Engine
The European Commission has issued a formal preliminary ruling against TikTok, alleging the video-sharing platform failed to protect users from content that exacerbates mental health struggles, including anxiety and eating disorders. This move marks a significant escalation in the European Union’s regulatory scrutiny of the platform’s core business model.
In a statement released on Friday, EU regulators characterized TikTok’s recommendation algorithm as potentially harmful. They argue the system systematically directs young and vulnerable users toward repetitive content that creates inescapable “rabbit holes.” While individual videos may be legal, the commission notes that cumulative exposure to themes such as body image, isolation, and restrictive eating patterns poses a tangible risk to user wellbeing.
The Failure of User Safeguards
The commission’s investigation suggests that TikTok’s safeguards are fundamentally ineffective. Investigators found that even when users actively signal disinterest in specific topics by selecting “not interested” or refreshing their feeds, the algorithm continues to serve similar content related to diet and body image.

Henna Virkkunen, the lead official on EU tech policy, pointed to the platform’s engagement-driven mechanics as the primary culprit. “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,” Virkkunen said. “TikTok needs to step up its efforts to protect users’ wellbeing, including those of minors.”
Collision with the Digital Services Act
The investigation, which began in February 2024, is being conducted under the Digital Services Act (DSA). This comprehensive legislation requires large online platforms to implement rigorous measures against systemic harms, ranging from the spread of disinformation to the promotion of addictive content.

Regulators are now targeting the design of the platform’s “For You” feed, demanding that TikTok provide users with more granular control over the content they encounter. A commission official indicated that the company’s emphasis on maximizing time-on-app creates inherent risks for minors and vulnerable adults, effectively placing the platform’s fundamental business structure at odds with EU safety mandates.
A Potential Six-Percent Penalty
This is not the first time the commission has clashed with the company. Previously, the regulator identified violations related to “addictive design” elements, such as the infinite scroll feature. At that time, TikTok rejected the findings as a “categorically false and entirely meritless depiction” of its operations, signaling its intent to challenge the commission’s assessment.
TikTok, which serves 189 million users within the EU, now has the opportunity to review the investigation file and prepare a formal defense. Should the commission uphold its preliminary findings, the company could face financial penalties amounting to as much as 6% of its global annual turnover. Alternatively, the platform may choose to reach a settlement by committing to structural changes in its recommendation system to satisfy regulatory requirements.
