I was one of the twelve banned for KAC 5.14 on May 4th 2009. Note: I am an Admin in this server. I was in spectate working on a clan roster.
Look at the ban list starting at 5/4/09 1:45am - 1:47am. All banned within 2 minutes.

I saw two players banned for KAC code 5.14. Those players were "Eat'Me'I'M'GummyBears" and "k4ng4r005 @ roohskill" - I was quite confused, because they were both in the server for quite some time.
Maybe a minute later, I got kicked and banned for the same thing. Eight more players got KAC'd for the same reason. I was the only admin at the time, and was talking to some members, about a roster I'm was building.
The following got banned by KAC (5.14) and unbanned by iPirate or Chrix (another admin)

Since I was banned so early, I didn't get a list (console) of all the KAC code. I tried to get them from another player, but his computer crashed. I'm 100% positive it was not admin. Like I said, I was in spectate, maybe another player trying somethign, but this was a very weird event that occurred.
(Edit: I stumbled on this looking for a detailed list of KAC ID's. Do you have those available for reference?)
