Well realistically you would just do your due diligence in each new partner site. Also it would be painfully inefficient to launder money like this, keep in mind you wouldn't even let people buy large quantities. In a real world scenario, you wouldn't even allow new partner sites to sign up online, instead you'd contact most of them via direct sales and vice versa. I'm thinking about the NYTs and Yahoos of the world, not cat blogs. I see your point, but this is more like buying world of warcraft currency than it is a bank.
