What if you were to say, make a macro saying your buying WoW Keys/Game Cards/ BC Keys etc... Then someone is gonna come along trying to scam you I'm almost sure of it...So tell them to give the code first or whatever, then say brb checking if it works, then odds are it's not gonna work especially if they sent first, so say it didn't work, call them a scammer, etc. Then from here, threaten to report them/whatever unless they give you X amount of gold. Just an idea haven't tried it yet or anything, and YES it's most likely bannable. Enjoy.
