Why does Square-Enix not sell subs for gil?

[Atelier-Bagur]

The matter of the fact is, they need to start banning the buyers. they take care of the RMT market, and suddenly the bots wont be as much of a problem. its really that simple. you start taking action against the player buying the gil, and buying gil no longer seems risk free or attractive. end of story. it works.

Buyers actually do get caught and banned actually. Yet we still have people risking it. Name one MMO where RMT doesnt exist. Go on, name one for me.
