Ban problems

Okay so today in server this player by the name of a dark avenger or player #7 was using bot in server. now i done !ban 7 no bots read rules permanment however got a usage error, i then kicked him with no bots as reason. he came back then i done !seen a dark avenger to try get a GUID off him, however nothing came up. He re-entered the server and i spectated him again and yet he had bot, so i tried !ban a dark avenger no bots 999d but nothing happened he stayed in server, i then kicked him again and again then tried banning him again but this time got an error saying player is ambiguous 5 matches, i looked on xfire to see who was on but nobody was on so i'll just keep on trying until he does get banned...

Did you:
!ban 7 time reason

?

u are a bit late with ur response. i banned him already
