Long time reader first time poster.
This was an old scam i used to do in EQ.
I was searching and could not find anything like this, only scams to actually scam game cards.
This is quite simple. Now we all know that there are a lot of kids that play WoW, kids do not have credit cards. I have run into countless kids that wished they could buy gametime with their excess gold. So....Get on your scammed account and go to any major city and offer to sell a wow gametime code for gold. Ask for a resonable amount, Like 200-300 gold or so. Use your social skills to earn trust and let them know that you have done this before many times. I believe game time codes are 16-digits long and follow this format:
xxxx-xxxx-xxxx-xxxx.
If this is a repost sorry, i couldn't find it.
