Okay, I'm lazy and know of a site that sells wow gold extremely cheap. I've used them twice to buy like a quick 2000g for mats, and crap.
Every time I use this site, though, they're instant to respond and be online. I always do a face to face trade and they're always online it seems like. They chill in the SW bank - they're mostly level 1 chars with random lettered names, and they're all in the same guild which also consists of random letters. I've noticed they do this for the guild bank so they can store gold and easily xfer gold from farming chars to the level 1 chars that sell them in SW.
Now, I've always been weary because these characters are just so obvious. I see them every time in the bank and they're usually targeting somebody next to them, which I think is funny. It's funny to see them in the act of selling gold. Why doesn't Blizzard catch on to this? You'd think they'd be easily found and banned. The first time I bought gold was a long time ago, and they're still there. But, on a another note, they've got reps that'll call your cell phone when they're online to give you the gold and they have called me instantly both times, and both times were from a California-based phone number with an American sounding person of the phone - no accents from what I could tell.
So, just yesterday I logged on and was questing in Sholazar and I saw a level 80 mage farming herbs and mining nodes, and he was in the same random lettered guild. I had found one of their farmers! I did a who of their guild and sure enough 4 other level 1 chars were online from the same guild, as well as 2 other 80s... both on Sholazar (one of the better places for mining, from what i hear).
I went to Armory and tried looking up the 80s profile and he was unlisted... odd, I tried looking up the other 2 80s both of which are unlisted. Obviously the 1s wont show up. So I looked up the guild, which exists, but shows no members.
Guild page hereAlso, when I sold one of my accounts like a year ago, prior to the paid name change - only xfer existed, I had used my xfer like 3 days before selling the account. I xfer'd the char to a server that my other chars were on (but on a diff account), and added the char I was selling to my friends lists. The same day that I sold my account, the char was removed from my friends list and either had its name changed, xfer'd off or was banned. I know, also, that banned chars remain on the server so they wouldn't be removed from my friends list.
All of this leads me to believe that Blizzard is profiting off the gold selling market, too! dun dun dun
