I don't understand how SE (all major companies for that matter) can't do a better job controlling it. It seems so simple hire a team of 10-15 people, and just have them go server to server checking towns for gold spammers and prime farming locations. If they see anything record it, kick player, ban account and move on to the next one.

At $30 bucks a pop gold farmers will quickly become unprofitable and those players whos accounts are being hacked will quickly learn to increase security.
