How Instagram is using AI to uncover teen accounts lying about their age

If your teen has a fake birthday on their Instagram profile to get around age restriction policies, their days of beating the system may soon be over. In a blog post, Instagram says that starting today it will use AI to detect users lying about their age and automatically move those accounts to one of the limited teen accounts that debuted last fall. First, it will monitor which profiles and content an account interacts with. Since people in the same age range generally enjoy similar content and interact with each other, if a non‑teen account interacts heavily with teen accounts and teen‑related content, Meta may flag that account. Second, Meta will review what it calls "strong signals of age," or things like birthday messages -- for example, if another user posts something like "Screaming happy 15th birthday to my best friend."
