All SE BLIZZARD and SONY has to do. Is create accounts themself. Sell them on ebay and to IGE. Then monitor them and then bust the buyers. Potential account buyers would be scared ********* And think tvice about buying.
They could also use sell gil plat and gold this way. Set up a website. Promote cheap currency. And nail the buyers one by one. They could also sell to IGE and others and bust the mules getting the gil gold and plat. That way you make a dent in the RMT business.
This way potential cheaters would be scared ******** of getting cheated when a new business starts up.
Rinse and repeat.
Rinse and repeat.
