seems dumb. there's nothing stopping a child from lying about their age anyways. how about parents who care about such things just block the TikTok app for their children?
if TikTok simply had an age selection box, and if you choose anything under 18 it said "too bad. wait until you're 18", I'm sure all of those children would say, "gee darn it, guess I'll wait" :eyeroll.
This sort of nonsense is why government's are trying to enforce age verification because god forbid your children go on a website or app.
at the end of the day these fines exist because it's easy money for the EU - there's really no way of stopping children from using TikTok, or any social media for that matter but the EU knows that so they fine the companies and keep the gravy train going.
