First time I’ve seen this sitting behind my shitty VPN. If the frontpage /r/normaldayinrussia posts didn’t make you raise an eyebrow knowing their denying access to people for running a VPN should at least make you second guess.
Get out now, save yourself.
Oddly enough it only pops up sometimes. I have a hypothesis that they don’t have a good list of VPN IPs try connecting to a different server.
Probably depends of if your IP is classified as a residential or a cloud or data center IP address.
Some VPNs do some shady shit to run on a VPN on a residential connection without the knowledge of residents. Of course, it’s also possible that their network policies leave out some VPN’s IP addresses unintentionally.
