OK so I finally figured it out, no person is doing this, it has nothing to do with rcon password
look at my servers ban lists,
http://slayersgaming.com/sb/index.php?p=banlist
notice something odd about the bans made by CONSOLE?
the console automatically bans players that have quotes ("") in their names, no one else
its put the part in the " " as the ban reason
player Saul "The Bear" Bereson banned by console, reason: Bear Bereson 0
player ☢"® Prophet™"☢ banned by console, reason:
player Grafik "Panda" banned by console, reason: 0
player Rainbow Dash "The Heartbreaker!" banned by console, reason: Heartbreaker! 0
player F_ck.Just need "U" banned by console, reason: 0
