It leads directly to the creation of a virtual black market (buying gold/credits) and virtual crime (you are cheating by buying gold).

And that black market spills over into the real world. People who run gold selling operations are involved in real world shady stuff. Real world black markets, real world crime.

And all of this seems normal to players. It's just how the AH works, always been that way. You're conditioned to it.

Just. Like. Society.
