So the UK is going to start requiring IDs to view adult content. I'm in the US, but I've got a friend in the UK who obviously doesn't want to deal with this.

I suggested he use a VPN, but he's apparently heard they sell your personal data. Can anyone recommend a reliable VPN that collects as little data as possible?

ETA: thanks for the suggestions, everyone! I'm gonna research em and pass the info along. :)
