It is possible to add a prepaid card or gift card to your account on our end, however many card issuers for these types of cards have policies that will not allow them to be used for recurring subscription sites or porn sites.
Theoretically, any Visa or MasterCard should work, but it just depends on the card itself. Unfortunately the list of different cards and issuers is too long, so we don’t currently have a way to track exactly which ones work and which do not, however the prepaid debit cards seem to have the best luck when using this option.
You are welcome to try any prepaid or gift cards by adding them under Account at the bottom of the left side menu, but keep in mind that you should only try adding it ONE time. Three declines, regardless of the reason, will lock your ability to add or use cards on the site for 24 hours and we are unable to unlock this feature for you.
