It was an asshole way to put it and I didn't read the comment correctly.

I read it as "I don't feel like looking for a payment provider/method" not "A payment method does not exist." Admittedly, I'm pretty ignorant as to adult site payment methods but it would seem that, for such a massive industry, someone out there is accepting payments, is it really each individual site handling CC info?

Bitcoin payments, not so much. :)

Yeah, I don't know if I want to make a billing service on top of a system that has no concept of refunds.

Sure it does. They send you back your bitcoins. And any reputable organization that accepts bitcoins as payment, would do so.

What it doesn't have is a concept of chargebacks, where you basically Indian-give your money.
