Works with silEnT mod only, bud. If no GUID player enters server running silEnT mod 0.5.0 and above, mod will autogenerate key for the player for XPSave and Admin.
You can also ban cheaters based on their hardware, IP and subnet. If you think, someone is cheating and continuously changing IP then ban their subnet using !subnetban

But if you have member playing from same subnet then whitelist the user based on GUID so that user can play.
