As Joss mentioned, the server possesses several admins that do understand Russian, even though it may not be proportional to Russians' share of the player base. The matter is rather that our server policies are not that restrictive in the points you mentioned.
Generally if we bothered to sanction every possible insult on the server here, I think administration would not get to fulfill its more important tasks. This is also how we held it in the past - if constant and targeted bullying of a person appears it's obviously another topic, but then you should point to such specifically.
Same goes for 'offensive' usernames - it is your own choice if you feel offended by the sheer sight of the name of a person you abhorr. The administration is neither willing nor capable to introduce political correctness on the servers, I may claim. This has always been our practice and there appears no reason to change it just now.
In turn, as I remember we always dealt strictly with players who used names that insult other players personally. If you are target of such, feel free to pinpoint it here (screenshots help).
If you want to lead a revisionist history discussion, this is probably not the right place to do so.
I hope this cleared some of your questions.
