I hate these guys... And its time for revenge. You know they're stupid so you can screw them however you want. You just need a friend that knows chinese or find farmer that talks english. Now write his name down (or add to friends list) and ask him to pay you or you report him a GM. Explain teh situation, like you'll get banned, account will die and your boss will cick your ass etc. If he says: F**k you, then you just report him. In 1 hour after GM reply ask your friend(s) to report him. He'll get banned for 72 hours of something. Then talk to him again and if the answer will be same just report him again. You know, its like some gangster business. Also you can scam these guys any way you want, since they dont know how to report to GM. Also if they DO report they cant do anything since they do illegal job in the internet. You won't be banned for this.
