? What does a MM have to do with anything.
You and MM and buyer agree to meet in wild and trade cash.
Buyer gets on msn and gets his buddies to stay at the selected trading spot.
You, mm and buyer all login and go to spot, Buyer calls in his friends, they kill you and MM, and steal the cash.
Buyer says that he doesnt know what happened.
You get scammed.
Terrible way to trade...
