This ban is a wake up call to Tech Industry to implement and enforce rules against hate speech, grooming, fake news, etc. They surely cannot verify the age of a human without any official ID made in the real world. This leads to other problems but that's not the concern of the government! Social Media wants it's users, not the government.

Government provided open id service which guarantees age. Website gets trusted authority signed token witch contains just the age. We can do this safely. We have the technology. They could even do it only once on registration.

Digital id's exist already in the EU, and many countries run a sign on service already. We aren't far from this.
