This is simple! Accept Bitcoin. Seriously, just accept it - if you don't accept it you are turning away free money. Customers paying for adult content LOVE USING BITCOIN. It's anonymous, there's no risk of cc numbers being stolen by an adult CC company (it's happened to tons of people, myself included), it just makes sense. You can IMMEDIATELY cash out your bitcoin into USD, it's simple, just accept it. I recommend Bitpay. I know of a few companies using them right now. I promise you, I will not renew with CC - but if you accept Bitcoin, I'll keep my subscription around. In fact, I will do my best to be your first Bitcoin customer, and not because I hate bitcoin, I hate spending bitcoin, I love saving it up because it's going to change the world. All of the problems your customers are having with being unable to use PayPal, you can FIX THEIR PROBLEMS by accepting bitcoin. I guarantee you a lot of these customers would LOVE to renew via bitcoin because of how anonymous and safe it is to use.
