You don’t need to ban literally any website that could be classified as social media to have the desired effect. You just need to ban the big ones: TikTok, Instagram etc.
Sure, but recall how this conversation started - we were talking about this specifically in the context of the Fediverse applying age-ID checks. It’s financially non-viable and any attempt to enforce it would force instances to all shut down. Not that it realistically can be enforced.

Because age-ID tools cost money to maintain. And most larger instances do not screen every single application individually. If it could be done financially without age-ID, it would certainly make running the instance a complete chore and cause many to shut down on that basis alone.
And asking people to give them a picture of them in a pub isn’t going to be accepted as a valid age technique legally.
