In my opinion, Bitcoin and Porn won't match each other due to the former's anonymity. Yes! Except legit and trustworthy sites like, Brazzers, Naughty America, etc. most other sites will turn out to be scammers and "ad-whores" since you can't claim anywhere that you bought an account there
On the contrary, it would be really helpful if the well-known sites start accepting BTC. But then again they won't do that, since there lies no proof that a 15 year old child is buying an account! That's why credit cards are a must for legitimate sites!

I know your means mate, yes, with bitcoin you can't provide if your age is over 17 years. maybe this is why porn company like Naughty America start to accept bitcoin again, it's like conspiracy theory

Well if you can see porn entertainment industry, it's big opportunity to use bitcoin as payment.
