I don't use TikTok, I never will (As a disabled person[1]). But age detection is a hard problem. Several years ago I was running a chat-app network' platform for privacy focused dating allowing communication between, Messenger <-> Telegram <-> Viber <-> LINE First major issue I ran into was that in SE Asian countries many used their children photographs for profile picture in chat apps, which obviously was a no go for dating, so I had to implement Amazon Rekognition to detect age, make those users change their profile picture and their profiles weren't displayed until it was changed. At peak it processed 200,000 images/month. But Amazon's model was biased and resulted in several false positives for darker skin color marking several adults as children; But since false positives were better than false negatives for this case I went on with it. Amazon told me that they are working on fixing their model, not sure whether it has improved.
