Sexual content on platforms is in such a weird place. It gets tons of views, but you can't have a platform that's
only adult content or it scares off advertisers. But if you have a successful platform that has adult content and you try to remove it, the platform becomes nearly worthless: see Yahoo and Tumblr. A mainstream brand like Visa has no issues advertising on Twitter, despite the massive amounts of adult content on Twitter. Yet you'd never see a Visa advertisement on Pornhub.
If you're running an ad-driven platform, you need to be in this weird Goldilocks zone where your platform has sexual content but isn't really known for sexual content. That's where Twitter, Twitch, Instagram and Reddit are, and it's why OnlyFans tried to push the "not just for porn" angle so hard for a while.
