Don’t get me wrong, I’m all for privacy. But between setting up the birthdate when creating my children’s local account on their computers, and having to send a copy of their ID to every platform under the sun, I’d easily chose the former.
I’d even agree to a simple protocol (HTTP X-Over-18 / X-Over-21 headers?) to that.
let’s follow the argument this is to protect children: why does is seem like a good idea to let everybody on the internet know what age your child is?
so if it is not to protect the children, what else could it be?
