Starting today, if Instagram’s AI detects that an account may be run by a minor—through various factors like birthday posts and account interactions—that user will automatically be placed in a Teen Account.

Instagram is expanding its use of artificial intelligence to determine if kids are lying about their ages on the app, parent company Meta Platforms said on Monday.

The company says 54 million teens have been enrolled in the age-gated accounts so far, and the same model was recently extended to Facebook and Messenger.
