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.
They basically want to avoid people creating accounts from behind VPN addresses that can’t be adequately policed for stuff like ban evasion.
They want your legit address so they can just ban your account and if needed your IP without having to hassle some VPN worker through whatever specific policy they have on cooperating with rule enforcement
The majority of people have dynamic IP addresses so that’s about as useful as a pile of shit and once again just limits legitimate access.
