Maybe at some point down the line, if someone does find a money/gil trader power-levelling some characters illegally, a long-standing "for the good of the community" person can go into "GM" mode & "Perma-Bind" (Bind, Amnesia, Silence) them & they can then petition a GM to "release" them after a full assessment is carried out. Basically, policing ourselves (Note if the "GM" power is abused by someone, they can be ejected from the game).
