And not just because somebody gets screwed. No, RuneScape's Imre Jele tells Eurogamer that gold trading is like prostitution because the worst part of it isn't necessarily the problem itself (most games can deal with gold trading in their economy), but all the other problems that come along with it-- gold farmers, illegal purchases, and so on. Jele says that stolen credit cards are often used to buy gold, and we've all heard of the working conditions and pay of many gold farmers out there.
Jele also says that he's taken steps to stop the gold trading by making unbalanced trades illegal in his game, and has called out other industry players to do the same. But finally, he lands on the real matter at the heart of the problem-- we have to aim at the reason players want to cheat in the first place. If you make games fun, says Jele, players won't need to cheat at all. We're not quite sure exactly how the prostitution metaphor holds up in there, but he has a point.
