I've moaned about cheaters before, so this time I thought I'd make a positive suggestion about what to do about it instead:
1. Put more resource into finding cheaters; currently this has just about zero effort from TK, who rely totally on player reports.
2. Find better ways to detect cheating AND/OR use better "algorithms" for determining who cheats are. Currently even many obvious cheats slip through the net.
3. Find better ways to punish the cheaters - something that goes beyond getting banned from one server, which has very little deterrent effect.
WHY should you do this? Because if you don't then players will either leave (already happening) or say, "if you can't beat them, might as well join them" (also already happening). All that will be left is cheaters... Bye bye TK.
