I think this server should has a alert system in play for the mods. This will allow them to see chat and it will send alert to the mods for example this player is getting 29cps constantly or this player has been banned (player name) possible ban evading. This might be helpful because mods cannot do anything about auto clicking or ban evading. Here is a example of the plugin in use @Herf
I'm not sure what type of plugin you was using however mineverse will most likely make a costume one if this go though.
Support, if we could get a plugin that would say if the player might be using Anti-Kb or flying it would help A TON when mods are looking for hackers. Hopefully Cyp would actually think about implementing it.
I support the idea, but as @CountryGirl_ said, it doesn't work brilliantly. Also, in a few hours, the developers on bukkit will be panicking, and frantically updating plugins.
