i think somebody who is already using a porn website that they like, should send them an Email with this suggestion. they should explain to them the advantages of accepting bitcoin and tells them about how they can do that. this way we might see them start accepting bitcoin as payment
Porn websites already know about the advantages of bitcoin. The advantages mean nothing if people aren't spending their bitcoins on the sites.
Porn websites are much more smarter and tech advanced then we believe and people have started using bitcoin on the porn websites and they would attract their customers by showing some promos that makes the customers to spend more and more bitcoins on the websites.
