| Bellow is the server rule. If the admin that banned you feel this applies to you then the ban will stay. You'll need to take it up with the admin who banned you. When was the ban imposed so we can check the log?
Racist and Violent Remarks
Absolutely, positively no racist or threatening remarks of any kind are allowed. There is no second chance on this, instant and permanent bans will be given out for anyone breaking this rule. It does not matter if the words are said in jest, or if they are written in anger, both will be treated in the same swift manner (permaban). This rule not only applies to in-game communication (both text and VoIP), but also player and squad names.
