If you want to avoid bad karma, why do you think complaining about it here-- a public place where surely nothing will get done? Don't you think calling a cheater out here or elsewhere is the same on the deep metaphysical level you are worried about?
Screw both rants and metaphysics, and be more direct. Make your case to the relevant authorities. Ideally, you'd approach the cheater and say "Listen, I'd rather ask you to cease and desist than I ask our show association to do that. What you say?"
