What kills me is that SE is more than capable of tracking down buyers and banning them. Look at the lottery fiasco. While it was a fiasco... it also showed that SE could really parse data across multiple server mechanisms (the lottery module, housing module, etc) and recreate what happened to then make it right in the end. If they are able to handle reverse engineering that whole mess but can't do something simple like tracing gil transfers between RMT and buyers?

I'll say it right now - if there were actions I could take in game that would get me banned, that would be enough of a deterrent to make me not throw away years of time spent on my character for ill-gotten gains.

Reminds me of some exploit in FFXI in some raid zone. There was some way to multiple drops or something like that. It was clearly an exploit. The players were warned not to do it and then the ban stick came out and destroyed many end-game raiders with wanton destruction. Go after the players and stop the RMT.
