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.

Eh—the draw of putting that content on Twitch is siphoning off part of a huge audience by sharing space on a popular non-porn platform. Separating the two would remove the reason people are streaming there instead of OF in the first place.

Amazon doesn't want to get into the adult industry.

I'm not sure how creating a more limited product (than OF), and reducing twitch viewership, would be innovative.

Horrible idea!

By keeping softcore erotica nudge-nudge on their video game streaming site, they allow viewers to tell their parents and girlfriends that they're watching games and chat. Spinning it off would kill the market for that content without doing anything for the video game side of the house.

They deliberately don't want that.

Twitch is the top of the "marketing funnel" to onlyfans for a plethora of onlyfans streamers: https://i.imgur.com/jeOq6ek.png

OF spammers have also completely ruined NSFW reddit, because the simp mods do nothing about it.
