Critics have raised concerns about privacy as well as access to the platform for users falsely flagged as underage.

YouTube began rolling out an 'age-estimation model' in the U.S. that uses AI to restrict access to users determined to be under 18 years old.

A new system within YouTube will use AI to monitor your history and the lifetime of your account to flag whether you’re under 18. If it thinks you are, you'll be moved to a teen account.
