Well, I think they may use the same position hack as for Twintania. I expect them to be banned sooner or later. It doesn't bother me really, yeah it is annyoing ppl using cheats. But what do you have? You get unsellable gear, some achievements but nothing which affects other players directly like crafting materials or so. And when the big ban hammer comes, it doesn't matter at all, they're banned then and cheating was for nothing.
The coil fights are just a challenge, nothing else. Beating them with cheats is dull.
