I must admit that I actually thought that they were referring to macros when someone qouted that line on this forum, but your explanations makes a lot of sense.
Besides, it seems very unlikely that Nutaku would bother to hire a person just to track down a few macro users, while only a few hunderd players are actually spending money on this game.

Well I am not a computer genius at all, so you guys wont have to worry that I will start using a program like that in the future
