Now you know, there is no moral here no rules, you can do banned anyone you want, without any evidence, only on the holy words of Nikita. I think you Admin should review your sense of fairness and impartiality.
In my opinion, you have to do something like giving a unban the forum. And do not print out that one of the members is not fair, or gave you banned for nothing. Rather, it will not help. Tell me what you got banned for and apologize for bad behavior. And as we react to that is no longer I'm sorry it's not their fault. If you got banned for something you probably can not be done or prohibited by the rules and principles.
