On November 6, the European Union’s technology regulatory body leveled serious allegations against the social media platform TikTok, alleging violations of the EU’s Digital Services Act (DSA).
The European Commission pointed out that TikTok’s recommendation system exhibits a phenomenon known as the “rabbit hole” effect. This effect occurs when users are continuously exposed to similar content, leading them deeper into a specific type of content without a way to easily escape. As a result, they are now demanding changes to the algorithm that underpins TikTok’s “For You” page.
According to the Commission, TikTok’s “For You” algorithm tracks user scrolling and liking behaviors, producing an incessant barrage of content that often revolves around themes associated with sadness, isolation, and body image issues. Such continued exposure to negative topics can negatively affect users’ mental health, potentially drawing them into a web of extreme and troubling content that is challenging to break away from.
For instance, if the algorithm consistently promotes extreme dieting, body anxiety, or distorted beauty standards, it could trigger mental health crises in adolescents, raising the risk of eating disorders.
Henna Virkkunen, the EU’s chief in technology affairs, stated directly that TikTok needs to adjust its business model in Europe. She emphasized the company’s responsibility to enhance the protection of user health and well-being, especially for minors.
Reports from Reuters and The Wall Street Journal indicate that the EU Commission has deemed TikTok’s previous risk mitigation measures ineffective. Additionally, the control tools offered by the platform have not granted users sufficient agency over their content consumption. The regulatory body has recommended several changes for TikTok to consider:
1. **Change Algorithm Metrics**:
TikTok should stop using “watch time” as an indicator for continually feeding similar content to users.
2. **Respect Explicit Preferences**:
The platform should place greater emphasis on user-defined preferences.
3. **Enhance Control and Testing**:
TikTok must improve accessibility and usability of user control features and conduct regular comprehensive testing of the algorithm.
This allegation is part of a broader, multi-year investigation by the European Commission into TikTok. Earlier this year, in February, EU regulatory authorities had already raised concerns regarding TikTok’s addictive design features—such as infinite scrolling and autoplay—as well as inadequate protections for minors and challenges faced by researchers in accessing data.
If TikTok ultimately fails to address these issues and is found to be in violation of the Digital Services Act, its parent company, ByteDance, could face steep fines of up to six percent of its annual global revenue. Furthermore, the European Commission is also conducting an independent investigation into the “rabbit hole” effects arising from the recommendation systems employed by Meta Platforms’ Facebook and Instagram.
In response to the initial findings, a TikTok spokesperson firmly denied the allegations, arguing that the European Commission’s statements are “fundamentally inaccurate” and misrepresent the platform’s structure and its commitments to user safety.
TikTok’s official statement emphasized, “We have a strong track record in protecting our community while allowing users direct and intuitive control over their content experience.”
The European Commission clarified that the initial findings do not predetermine the final results of the investigation and that TikTok will have the opportunity to formally respond and contest these allegations in due course.
