IMO the real solution to preventing kids getting into adult content is for Governments to agree on and enforce a universal set of parental controls that every program and website has to respect. Put the onus on parents to make sure their kids aren't doing that stuff.

But that's not the world we're working with. Instead Governments have decided they're going to play nanny, and it would appear nobody is taking no for an answer.

So from a practical perspective, if I'm going to have to play along, I'd much rather my own computer handle my sensitive data locally and prove my age for me, than multiple fuckwits' servers off who-knows-where holding onto that data per website I want to visit.
