If you kick someone, they are allowed to rejoin. Kicking them again because they come back is abuse. Banning them afterwards because they came back yet again is more abuse. PEOPLE ARE ALLOWED TO REJOIN IF YOU ONLY KICKED THEM. There is no rule stating they are not allowed and you are not following your admin guidelines. You are wrong, plain and simple. You are interpreting rejoining in your own way. If you don't want someone coming back for rejoining, ban them right away, but then again, that is not how you are supposed to do things, you should issue a verbal warning. His team attacking has nothing to do with his initial kick nor does it have to do with his ban. You using admin to slap him because he team attacked you is also abuse. You should read the admin rules again.
