Its too bad PornHub accepting Bitcoin is seen as a reaction to them getting blacklisted by mainstream payment processors. Makes BTC seem like the "sketchy" alternative. IMO Pornhub WAS doing the best job at being a "mainstream" porn site. Any sites that allow users to upload content is going to have the problems they had. YouTube even has those types of problems...
That being said, tons of content producing porn companies have been accepting BTC for years. Most of the major studios do. Verotel (one of the largest payment processors for small niche studios) used to accept BTC as well. Unfortunately they stopped when Bitpay stopped allowing adult services. I suspect with verotel at least 1000+ adult sites were able to accept BTC. I've been trying to bug them to find a way to accept it again... Hopefully this most recent bull run does the trick.
If you're curious what porn sites accept BTC right now you can check out a site I've been putting together:
