I really think socialmedia is no good for kids at all. I agree, that kids should have restricted to no access to social media.
I am simply not happy with mass surveillance. So I do not agree with mass ID-verification.
Sensitive data (all identifying data) should be collected scarcely and deleted as quick as possible.
But social media is a dsctraction for kids. Kids brains are much more vulnerable to addiction. And they should be protected from it. Usually I expect this to happen from parents side.
