I blacklist them all,at first you won't think it is working,but after a week or so they will get less and less.Also let me pose a silly question as follows.How come they can't get the logs or search them or whatever,you can't tell me Square Enix doesn't have the means to do anything.I can only speak for myself,but RMT bots totally Ruin an otherwise fun and awesome game,furthermore if you buy Gil from RMT you suck,and are part of the problem.Why play a game if your just going to cheat.
