Today was contacted by in game MOD inform me that my guild tag [MOFO] was not appropriate but [ASS] is allowed.
ASS mean small donkey by the MOD
MOFO also mean "Morning Formation"
In a more direct explanation is abbreviation.
Well this is just my 2 cents of knowledge and posted here because was not happy when i spend 200 EURO in a game and now i feel like quit the game and get back to a more ENGLISH understanding game.
