Perhaps the most perverse consequence of age verification laws: many require advertising the age bracket of the user to the open web. Children will be known to be children even to those that would exploit that information without regard for any other "safety" law.
@carlrichell whilst I agree with this whole heartedly the one small area that I believe age verification may be helpful in society is in social media, it's clear that unfettered access to it has poisoned young minds and I see it daily in the youth I work with. In EVERY other area, age verification is useless and harmful. To which, the only real solution is for parents to make the correct effort to restrict that access.
