Well... while Visa might have been rebuked by this ruling, I should think that CCBill or Epoch, for example, could have their own internal policies that say they choose not to process for sites with stolen content, in the same way that they have the option of not processing for sites they consider offensive or whatever... things like pissing, the "artistic child nudity" sites. Given that those sorts of sites are processed by some of the shadier processors like Segpay, it's clearly not a Visa regulation, but an individual IPSP's interpretation of Visa's regs.
