I can confirm this, I cannot use my polish card to enter US porn sites. And other polish webmasters confirmed the same
Both CCbill and Epoch decline polish cards by default. You could have a card with the highest limit, but it would still be declined.
From US processors only Jettis and - very rarely - Ibill accepted polish cards. But Jettis merged somehow with Epoch I think and Ibill...everyone knows the story.
European processors accept polish cards with no problems though.
