A few players on my servers have complained that they have been randomly kicked while playing but not banned and it doesn't say why they were kicked all it says is
Disconnect: Kicked by Console : You have been kicked by this server, check http://www.trident-gaming.net/sourcebans/index.php for more info..

I have also looked through the KAC log and there is no mention of the kick in it.
