Trying to get the most out of a game simply by using mechanics that are in the game is not cheating.
Of course. But we're not talking about mechanics, but about glitch. Someone used glitch, ok, he could think that this was intended by the devs. But when devs fixed that glitch, and someone want it back claiming that "ok, it can make you overpowered, but some people like it", im pretty sure we can call him cheater.
