European Union regulators accused TikTok on Thursday of breaching digital content rules because it’s not being transparent enough about ads shown to users of the video-sharing app.

TikTok’s ad repository isn’t up to the standards required by the bloc’s Digital Services Act, known as the DSA, the 27-nation EU’s executive Commission said in preliminary findings from its investigation.

The Commission said ad databases are vital for researchers to detect scam ads and so-called hybrid threat campaigns, coordinated information operations and fake ads, “including in the context of elections.”

The Commission said TikTok doesn’t provide necessary information about the content of ads, the users targeted and who pays for them. — Associated Press
