What? Bitcoin is perfect for porn sites because of its anonymity. If porn sites started ripping you off then they wouldn't survive for long with such a bad rep. News would quickly spread that people wernt getting what they paid for. Most sites will probably use a bitcoin payment processor too.
How will they verify your age if they adopt bitcoin as the payment system? Most legitimate sites out there won't let you get access to their stuffs without verifying that part to prevent getting their licence getting banned!
BTW, why do you worry about paying through credit card? They won't disclose your personal information
