Of course piracy is one of the biggest problems, among other things. But as everything becomes more and more seamless, paysite joins still require you to locate your pants and wallet, whip out a card and fill in a form with CC info, name, maybe address, etc. Probably losing your boner and drive in the process.
Look at how easy it is to purchase an app on an iPhone or Android market. You just click a button and hardly have that feeling of buying something.
Why has the adult paysite community still failed to put together a widely used seamless payment solution? I think it would be really surprising how many more sales would be made if the person could signup with one hand.
