Thank you http://www.mmowned.com/forums/wow-sc...seriously.html for giving me the idea, especially soul eater.
The scam is very simple.
1. Find a gamecard code that wasn't used too long ago. Shouldn't be too hard to find, example: http://www.mmowned.com/forums/accoun...ime-codes.html <--Don't use those though because some of them have been used by mmowned members.
2. Go find one of those "Duplicate your gamecard" things on youtube.
3. Call the billing department, and tell them that you have been scammed out of your Gamecard by the youtube video.
4. The blizz employee should then ask you for the code.
What this will do, is they will track down the account that is using that code and give him a warning/ban, and will give you your gamecard back / a new one. (Theoretically, not tested yet*)
I have not tested this, so you might end up needing some proof of purchase like a reciept, although I have no Idea how that will work over the phone.
Anyways, just trying to contribute, tell me what you think.
The person over the phone will not say "You were trying to scam us by using the youtube thing, kthxbai."
The people that work there are getting paid to help you.
Therefore, they will help you, and not get you banned.
