There isn't any real way to actually ban them because FF14 doesn't have malware etched into it to see your running programs like other MMOs do. It would be based on manual reporting and people that were actually playing might get banned for being too good, although it is painfully obvious to tell when a program is being used.

Really the only solution would be community driven. The other day I saw a bunch of people hyped up about someone playing a Dragonforce midi saying "Omg they're so good", and me and a few others explained it they were using a program, but there are people that are actually good. If someone's using a macro I just walk away but will stay and listen if they aren't.
