You don't even have to go that far, in Europe, to use a large social network (50M users), and the definition is very broad (WhatsApp is a social network, Telegram, Signal, TEMU, Aliexpress, etc), all users will have to provide their ID to that they are not a minor, otherwise the website can be blocked or fined.

This is to protect minors of course. Did you think about the children ?

Telegram, whether it's true or not, claims they are not a large platform (so if this is a lie, it may really pay off).
