Yeah. I've shared my own suffering due to cheating in MMORPG. and it sucked dammit.
Fly Hack
-dammit, they fly above the sky and can't be hit. you suddenly die without seeing your enemy
One Hit Hack
-bosses die in an instant. characters too.
Dupes
-duplicating items and in game cash. them guys aren't afraid to upgrade since they have limitless resources.
Speed Hack
-them attacks too fast.
It was a terrible time for us, many quit playing, but there were some who stayed. I think the patch when it happened was appropriate "Crimson Dawn". Bugs were abused. there were a lot of players getting perma ban. lasted for about 6 months.
but i'm glad that was over even before the next patch.
so we shouldn't allow cheating in GBAtemp.
