Credit care will just expose your personal details in a certain porn sites
You should never use a credit card to purchase porn subscription. If you are that desperate, use a prepaid debit card with no personal information. But using a CC is extremely risky, as these porn sites get hacked every now and then.
People get scammed because of credit card use, and they also get their credit cards stolen and then people sell them on the dark web, it's very unfair but that's life. I think bitcoin is the ultimate way to pay for porn, every porn producer would benefit from accepting BTC, I can't believe they aren't all into it already. I guess it will take more time. I think with the invention of VR Porn it will be huge in the future.
Porn producers are not that averse to accepting payments in Bitcoin. But logistical and legal challenges are preventing them from accepting the BTC payments. Bitcoin payment processors such as Bitpay normally reject requests from porn websites to process their payments. Also, the legal aspects of accepting BTC payments for porn subscription is still very murky.
