They simply lead you along with prices too good to be true (because they are not true) and take your money then shut down the site for a while.
I have friends in Homeland Security looking into these pigs. Maria Green and her fat co-conspirator, Adam.
They use Chase Bank for money transfer and a call to the bank in question got me nowhere. They refused to put any kind of a hold on the account and would not even admit that the account existed even though the transfer went through. I told them a crime was being committed and they laughed in my face. Chase had time to look into it and refused. They are just as culpable. I would avoid a bank thay protects criminal activity.
