route everything through a vps?

It's not a full solution. I've seen UK sites that, following the Online Safety Act, simply require all users to verify their age rather than bother to figure out whether you are actually a UK customer or not. I guess it's easier to implement and many sites mainly rely on domestic customers anyway so they don't care if international users are affected.

Also, this isn't just about porn. For example, I can barely use Reddit now if I connect with a UK IP address: the merest hint that there might be some NSFW angle to a post is enough to trigger their algorithm into requiring age verification.

It's a temporary solution though. It's only going to get more draconian. Next thing you know the talk is about punishing VPN users, because now they can be painted as evading the law.

I would much rather fight this and retain my rights instead of participating in some kind of privacy and censorship arms race.
