Hi GOJIRA, Welcome to Vogon!
There is a auto ban system in place to insure that hacks/cheats are removed from the server for excessive score difference when live admins are not preset in the server.
You were auto banned for excessive score difference.
When playing on any of the Vogon servers it's up to the players to control their game play so they don't get the dreaded auto ban as in your case.
If you've checked our server stats on Gametracker you know that the ARES TDM ANARCHY Crk. Server is the #1 world wide COD4 server.
Because of the high volume of Players that we get yearly the auto ban system is a necessary tool on the Vogon servers.
GOJIRA, dyn is the only one here at Vogon that can unban a player even if they have just been auto banned for score difference so unfortunately until dyn reads this post you'll just have to sit out the auto ban.
PS: Your suggestion for a ban list has been considered before, however the list is so extensive that it would take another copy of this forum to list all the banned hacks/cheats that we get yearly.
Have a look at the link below.
