Pornhub needs to do ethical marketing because their product is unethical. They need to pretend that Porn is healthy, normal thing. In fact, it's a highly addictive supernormal stimuli causing millions of men around the planet to struggle through the hell of porn addiction. I know others don't see it this way, but to me it's as clear as day.

The porn industry (probably with the help of Mindgeek), lobbied to change the law around teen porn, making it lawful to have girls acting like they're teens in porn movies. This, of course, leads some down the road to child porn.

But you're right, they're great marketers. They've donated tiny amounts of money (The owner of Mindgeek is worth $2billion), that make it seem as though they're ethical.

As people increasingly begin to realise the unethical sides of porn, you can be sure that Pornhub will increasingly put out ethical marketing to protect their brand.
