What classes a player as a cheat? How certain is the plugin that a player is cheating? I have had three players complain about being banned by this plugin. I want to use it but am just not sure how to turn off the auto-banning.

there is no auto banning, i'd suggest you have server armour running maybe?

It does ban some players, Im not sure why though if its becasue they try to type somthing into f1 or a terrain or some kind of violation.

The message the player gets

Rejecting connection - You are banned from this server (Cheat Detected!)
