Considering you have to e-mail people this to get htier account in the first place, most likely you will endup robbing friends or familys accounts rofl, plus they will just cancel the payments to it and report it as stolen to blizzard, at max you get one month free account and any items, weapons money etc in account (assuming they on same server you play on, not sure if you can send items to different world servers).
lool but it's difficult to find someone who is willing to log in with his account, especially when he's on a high level. the chance to get an useful account is low xD
And it wouldn't be hard to get people to run that wow.exe instead of their own, you just tell them, hey this exe gives you a built in wow glider, and they will use it for sure.
