My friend (Mr. Pickles) got kicked from one of the servers for saying "NIGGA" in a non-serious way, and now apparently the IP I use is banned and I can't get in. I understand that racial slurs is a no-no, and I apologize for his tactlessness. Is there any way lift this ban?

My Steam ID is STEAM_0:0:23483986

The name I use in-game is Enemy Of God

Thanks in advance.
