I asked that same question without a solid answer. I don't get how the ad benefits them in any way. Unless someone is stupid enough to send them Money to hold it or something.
well... i have no clue. i know this has been discussed at length in another thread.. but basicallly it boils down to getting money out of someone sight unseen. yes you have to be dumb but yes he could easily get say a 1000 dollar deposit out of someone.
