Ok, I know this is NOT the place for this, and It's ok to move it, but leave it open here for a few days please.
I know others have heard of this new hack, but I wanted everyone to be aware of it. Not sure exactly how it works, but just heard it is working!!!
This involves IN GAME trades.
The hacker will offer good items for what your selling usually more than you can do in one trade. At some point he will get you to involve another person, one of your friends... either by saying he wants someone to moderate the trade, or he doesnt know you so he wants others involved, or whatever...
He then ask you to give the item your selling to your friend. Somehow he then dupes your name in trade and ask for the item back (the hacker now has your name in the trade window with your friend so your friend thinks its you). He then trades the item to the hacker.
Be very careful if someone ask you to have a friend or someone else help!!!
