However, you can use IP changer.a few problems with this
1. you need the gold before hand whilst the TCG scam gives you the gold
2. you have to keep switching accounts because blizz would catch you if you did it more than once with the same account
3. you're gonna need a lot of neighbors with unprotected wireless networks for the reason above (cept with IPs)
not a bad idea if you have a few accounts sitting around but i still dont think that it's great for the average scammer. +Rep for it though.
