TikTok is ramping up penalties for creators who post potentially “problematic” content and tightening its rules around what can be recommended in the app. The updates arrive as TikTok is fighting for its future in the United States and trying to convince lawmakers and regulators that its app is safe for teens.

Under its updated community guidelines, set to take effect in May, TikTok has added a long list of content that’s not eligible to be recommended in the app’s coveted “For You” feed. The list includes some obvious categories, like sexually suggestive or violent content, but it also adds topics that have previously been a source of controversy for the app. For example, the new guidelines bar videos showing “dangerous activity and challenges,” as well as many types of weight loss or dieting content. It also prohibits any clips from users under the age of 16 from appearing in “For You.”

There’s also a lengthy section dedicated to a wide range of misinformation and conspiratorial content. From the guidelines:

In addition to the eligibility changes, TikTok says it will also begin to penalize creators who repeatedly disregard this guidance by making their entire account ineligible for recommendations, not just the specific offending posts. The company will also make their account “harder to find” in search.

Additionally, the app is getting a new “account status” feature, which will help users track if they are running afoul of these rules. Much like the feature of the same name in Instagram, TikTok’s account status will alert creators to strikes on their account and posts that run afoul of the app’s rules. And an “account check” feature will allow users to track if they are currently being blocked from recommendations or otherwise unable to access features like messaging or commenting as a result of breaking the app’s rules.
