Don't. All russian "VN translation groups" are chucking out crappy AI-translated slop to make money off other people's works with zero effort. Don't encourage them, don't make any deals.
I'll tell you how to tell them apart. They have a boosty - they are scammers as described. All good russian translations of VNs and especially FVNs were made by enthusiasts for no profit.
DO NOT FALL FOR THE SCAM.
