EU Tells TikTok to Fix Its ‘For You’ Feed After Finding ‘Rabbit Hole’ Effect That Can Harm Mental Health

TikTok’s “For You” feed can pull people into endless streams of videos about sadness, loneliness and body image — and the European Union says the company has not done enough to stop it. On Friday 6 November 2026, the European Commission formally accused TikTok of breaking the EU’s digital rules and told the platform it must change the design of its feed.

The findings are preliminary, not a final verdict. But they are the strongest step yet in a European investigation that has been running for more than two years, and they carry a serious warning: if the Commission confirms its findings, TikTok’s owner ByteDance could face a fine of up to 6% of its total worldwide annual turnover.

For the millions of people who open TikTok every day — including a huge audience in Pakistan, where the app is one of the most popular social platforms — the case raises a simple question. When an app learns what holds your attention, who is responsible for what it shows you next?

What the EU found

The European Commission is the EU’s executive arm, and it acts as the bloc’s tech regulator. Its case against TikTok is brought under the Digital Services Act (DSA), a wide-ranging EU rulebook that requires large online platforms to do more to tackle harmful and illegal content.

On 6 November, the Commission issued what it calls preliminary findings. In plain language, that means its investigators have looked at the evidence and formed a view — but TikTok still gets a chance to answer before any final decision is made.

The Commission found two problems with TikTok’s “For You” feed, the screen of personalised videos that greets users when they open the app.

First, it said TikTok failed to properly assess the risks of its recommendation system. The company did not adequately study how its algorithm could push users into repeated exposure to the same kind of content, again and again.

Second, it said the safety measures TikTok did put in place were not good enough. TikTok has added tools such as a “Not interested” button, meant to let people tell the app they want less of a certain kind of video. The Commission said those tools do not work well enough in practice, because the algorithm keeps paying more attention to how long someone watches a video than to what they explicitly asked for.

The result, the Commission said, is the “rabbit hole effect”. Every time a user scrolls or likes a video, the algorithm serves more of the same. When the subject is sadness, isolation or body image, that stream can be hard to escape — and endless, repeated exposure can harm users’ mental health, including that of children and teenagers.

“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,” said Henna Virkkunen, the European Commission’s executive vice-president for tech sovereignty, in a statement announcing the findings.

“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.

What is a “rabbit hole”?

The phrase sounds strange, but the idea is simple. Imagine you watch one video about feeling lonely. TikTok’s system notices that you watched it all the way through, and maybe that you liked it. So it shows you another video on the same theme. You watch that one too. The system takes that as a sign you want more, and the next video is even more similar.

After a few minutes, your whole feed can be about one subject. The videos get more intense as you go deeper. That is the rabbit hole: a chain of recommendations that keeps narrowing until it is very hard to climb out of.

This is not an accident. It is how the system is designed to work. TikTok recommends videos using signals such as how long someone watches and which videos they like. The longer you stay, the more videos the app can show you — and the more advertising it can sell. But when the content is about weight loss, sadness or mental health struggles, the same design can become harmful.

Research by Amnesty International in 2023 gave an early warning of this pattern. In a technical investigation, the organisation set up test accounts designed to simulate 13-year-olds. After a few hours of engagement, the accounts were shown a high volume of mental-health-related and potentially harmful videos. The EU’s investigation has now reached a similar conclusion through its own formal process.

The problem is not that any single video is illegal. Most of the videos in a rabbit hole are not banned content. The problem, in the Commission’s view, is the system itself — the way the recommendation engine keeps serving more of the same, even when the person watching may be struggling.

What the EU wants TikTok to change

The Commission has not just diagnosed the problem. It has set out the changes it considers necessary at this stage.

TikTok should give much more weight to what users explicitly ask for — for example, when someone taps “Not interested” or chooses to see less of a topic. At the moment, the Commission says, how long a person watches a video can outweigh their stated preference, so the button does not do what people expect it to do.

TikTok should stop using viewing time as a signal for recommending content. Watching a video to the end can mean many things: curiosity, shock, or simply that the phone was left playing. The Commission says it should not be treated as proof that someone wants more of the same.

TikTok should make its user controls easier to find and easier to use, so that people can actually shape their own feeds instead of hunting through menus.

And TikTok should regularly test its algorithm, so that problems are caught and fixed rather than left to run.

Taken together, the Commission said, TikTok needs to change the design of its “For You” feed — and, in the words of the Reuters report on the announcement, to change its business model in Europe.

What TikTok says

TikTok has rejected the findings. In a statement, the company said the Commission’s conclusions were wrong and unfair to the platform.

“The Commission has made a series of statements that are fundamentally inaccurate and distort our platform’s architecture and our commitment to user safety,” TikTok said.

“We have a strong record of protecting our community while giving users direct and intuitive control over their content experience,” the company added.

TikTok will now have the chance to examine the Commission’s investigation file and reply in writing. The European Board for Digital Services, which brings together the EU’s national digital regulators, is being consulted at the same time. Only after that process will the Commission decide whether to confirm its findings and impose a penalty.

If it does confirm them, it can issue a formal non-compliance decision and fine TikTok up to 6% of its total worldwide annual turnover. Reuters reported that ByteDance risks such a fine next year unless it can resolve the issue.

It is worth being clear about where things stand. Nothing has been finally decided yet. The word “preliminary” matters: it means the Commission has made its case, but TikTok has not yet had its full say, and the final decision could look different.

Why this case matters beyond TikTok

This is not the EU’s first clash with TikTok. The Commission opened its investigation into the platform more than two years ago. In February 2026 it issued an earlier set of preliminary findings, accusing TikTok of addictive design features that lead to compulsive use by children, of failing to protect children properly, and of making it difficult for researchers to get access to public data. TikTok called those findings “categorically false” at the time and said it would challenge them. This year the Commission has also issued findings accusing the platform of failing to protect children’s privacy rights.

The new findings are different in one important way. They are the first EU case focused directly on the design of a recommendation system itself — on how the algorithm decides what to show next — rather than on a single feature or policy.

And TikTok is not the only company in the Commission’s sights. The EU is separately investigating the so-called rabbit hole effects of Meta’s Facebook and Instagram recommendation systems. The outcome of the TikTok case is likely to shape how those investigations are handled too.

The pressure on social media companies is growing worldwide. Governments in several countries are worried that these platforms are contributing to a mental health crisis among children, and some are imposing or considering age limits and bans for underage users. The EU’s action is part of that wider shift — from asking platforms to remove individual harmful posts, to asking them to redesign the systems that decide what billions of people see.

For users in Pakistan, the case is worth watching even though the EU’s rules apply in Europe. TikTok is hugely popular in Pakistan, and design changes forced in one major market often spread to others, because companies usually prefer to run one version of a product rather than many. Pakistan’s own telecom regulator, the PTA, has also been active on social media apps: on 6 November it clarified that a viral notice claiming a TikTok ban in Pakistan was fake, while announcing that it had registered the apps BIGO LIVE and Likee. The debate about how these platforms should work is not limited to Europe.

What happens next

TikTok will study the Commission’s file and submit a written reply. The European Board for Digital Services will give its view. The Commission will then decide whether to confirm the findings, drop them, or change them.

If the findings are confirmed, TikTok will have to redesign its “For You” feed in Europe and could face a fine of up to 6% of its worldwide annual turnover. If TikTok can show that the Commission’s analysis is wrong, or that it has fixed the problems, the case could end without a penalty.

Either way, the process will take time. The fine, if there is one, would come next year rather than now. What has already changed is the direction of the argument: the EU is no longer only asking TikTok to take down bad videos. It is asking the company to rebuild the machine that chooses the videos in the first place.

How to take more control of your feed

Whatever the regulators decide, there are things users can do today to shape what TikTok — and other short-video apps — show them.

Use the “Not interested” option. When a video appears that you do not want more of, long-press on it and choose “Not interested”. Do this every time, not just once. The signal gets stronger with repetition.

Refresh your feed. TikTok has a “Refresh your For You feed” option in its settings. It resets the recommendations so the app starts learning your interests again from scratch. If your feed has drifted into a narrow subject, this is the fastest way out.

Follow accounts on purpose. The algorithm pays attention to who you follow. Following creators on a range of subjects — news, sport, cooking, science — gives it a wider picture of what you like than a single topic ever will.

Set a time limit. TikTok lets you set a daily screen time limit in its settings, and it will remind you when you reach it. Shorter sessions make it harder for a rabbit hole to form in the first place.

Talk about it. If a child or teenager in your family seems stuck on one kind of content, or their mood changes after long sessions on the app, it is worth a conversation. The feed is designed to hold attention; knowing how it works is the first step to using it on your own terms.

Frequently asked questions

Has TikTok been fined by the EU?

No — not yet. The European Commission’s findings are preliminary. TikTok can reply in writing, and the Commission will only decide on a fine after that process. If a fine is imposed, it could be up to 6% of TikTok’s total worldwide annual turnover.

What is the “rabbit hole effect”?

It is what happens when an app’s recommendation system keeps showing you more videos on the same subject, one after another, until your whole feed is about that one thing. The EU says this can be harmful when the subject is sadness, isolation or body image, because repeated exposure can affect mental health.

What does the EU want TikTok to change?

The Commission wants TikTok to redesign its “For You” feed: give more weight to users’ explicit choices, stop using viewing time as a recommendation signal, make user controls easier to find and use, and regularly test its algorithm.

Does this affect TikTok users in Pakistan?

The EU’s rules apply in Europe, not in Pakistan. But design changes made for Europe often spread to other markets, and the debate about recommendation systems is global. Pakistan’s telecom regulator, the PTA, has also confirmed there is no TikTok ban in Pakistan.

What has TikTok said in response?

TikTok rejected the findings, saying they are “fundamentally inaccurate” and distort both the platform’s design and its commitment to user safety. It says it has a strong record of protecting its community and giving users direct control over what they see.

Conclusion

The EU’s case against TikTok is about something bigger than one app. It is about who decides what we see online: us, or the algorithm.

For years, the argument about social media was about individual posts — take this one down, leave that one up. This case moves the argument to the system underneath: the recommendation engine that quietly decides, millions of times a day, what appears on the next screen.

TikTok says its system already gives users control, and that the EU has got it wrong. The Commission says the controls do not work, and the design must change. The next stage of the case — TikTok’s written reply, and the Commission’s final decision — will settle that argument, at least in Europe.

But the question behind it will not go away. Every time you scroll, the app is learning. The EU’s message is that learning is not neutral — and that the companies behind these systems are responsible for where their recommendations lead.
