i agreed with what card said, sometimes its a bug.. it happened with me in other servers (not from ambrosia) i joined the server again and asked the admin why he banned me and he said.. uh?? who banned you? and later we found out that it was a bug. That happens in ambrosia too a player had the same problem when i joined ambrosia. That can happens, and agree too with the ip ban, it is a mistake from the 2 parts, from the player and the admin, the admin should banned the players ip.
