I'v tried out a few way's to "attack" the victims now, but i havent had eny luck yet. A precice guide on how YOU go forward to catch the "custumers" would be superb.

enyway, for a scam with good potential, and obviously allready resaults.
Edit: Think i would give an advice. Take every person, and decide how high price you wish to give him. If you find a serious person, you can go for high ammounts of gold, the only downside with this "person" is that he's hard to find (a serious person, who belives you). The other "person" is the "noob". He seems willing to buy the key, but he probobally dont have much gold. Then you should try with a bit less gold (1000 or so), and you have a highers success rate. I just pulled inn 750g, wich is not bad for 4 mins of talking with some random "noob" xD
