I actually had the same exact problem about a month ago-I tried to purchase a Pornstar Network membership with a OneVanilla prepaid Visa card. After two attempts at submitting the payment information, I wasn't being redirected to another payment processor, so I was unable to join. Meanwhile, I had no problems using the same card to purchase memberships to New Sensations, Dogfart Network and Brazzers. I figured I wouldn't have a problem purchasing any memberships using the card, being that it's Visa, but apparently you're unable to make online purchases with it if the billing processor is based outside of the United States.
