I've found a few autoclickers on different servers there, you should add a anticheat for that, if they use a free one like autoclicker.exe from sourceforge you can add a script where it'll detect clicks from the mouse instead of just clicks.
There is currently an anti cheat on Kitpvp, you also get kicked for using an auto clicker. If you see or suspect someone is hacking, Then make a player report or tell your suspicions to a staff member so they can handle the situation
