I should add StormPay to the list. They are still registered as a business, but they are more now for auctions and their StormClix site until they can get out of under the fiasco with 12DailyPro.
People do not realized that transfering money from one payment system to another like from Egold to PayPal and vice versa constitutes money laundering. Add HYIPs into the mix, and you would get a hugh mess.
