FairFight: banned code #RSuhf1

Got a ban with that name. The name of the server was exactly the same as the official one, but there was an owner with a strange nickname. I thought I was banned by the administrator, but rummaging through the Internet I saw the news that cheaters at the beginning of the year were able to capture the official servers. On other servers, I can safely go and play, but not on this one. I can't figure out if this is a bug, did the cheater take over the server or did the admin ban me? Server #12001900
