I know they will do something to stop it. But banning... what for? This doesn't go beyond the game and console functions. There's no hacking or extraneous software used. I don't think there's an actual violation of their usage policy. If a game has functions that can be used in an unprofitable way for its developers - this is their own problem, not player's.
Really doesnt matter what you think. It fits the definition of exploit which puts the ball in their park. What you said is nothing more than a thin and rather poor attempt at justifying actions that you know to morally, ethically and legally questionable.
