I was just trying to access Feddit.UK via a popular VPN. It looked like the site didn’t even exist. Just a gray error page.
I’m not sure this is a good policy.
EDIT: I have clarification from ProtonVPN about what the problem is with accessing Feddit.uk. They have a service called NetShield which blocks IP addresses associated with malware and trackers. There is a false positive for Feddit.uk. Their team is aware of it, and will hopefully fix it. In the meantime, people can access Feddit.uk using ProtonVPN by turning NetShield off. It works for me.
Tom would need to comment on this. It could be it’s a balancing act (blocking IP blocks where bad actors have been seen, vs allowing genuine users).
It’s also possible that the instance host provider blocks certain ranges by default.
