Right. I get that. That's terrible. But you also seemed to be saying age verification + anonymity is impossible and I've been having this talk about this with a few people because of a new bill in Canada and it does seem possible... just imperfect.
It is not possible to do age verification to a significant enough degree of confidence in a way that protects anonymity. It can't be done. Anyone who tells you otherwise is lying to you. It is fundamentally impossible.
