ive heard of something similar to this. what u do is u make a noob with a name that looks exactly the same as ur main, whisper who theyre married to and say like "hey this is (yadda yadda), im in lab and need to borrow a couple of dbs to buy this item" or something along those lines. then they trade u, and there u go, free money =P
but obviously u need to know who theyre married to, and im not sure if this works anymore cuz they keep changing the text. try zero and capital o, or one of those tricky space things at the end.
