If they kinda allow making transactions and payments by cryptocurrencies why not other altcoins that support micropayments and speedy confirmations, they can do an ICO about porn creating their own coins over the blockchain for their own business, it is better for that way if they want to shift their industry over the cryptocurrency innovation. But for me, they just have to stick to traditional mode of payments the convenience is there.
There are several porn related tokens.
The first was SexCoin back in 2014. Since then I've seen more and more stepping forward.
