No, I truly think it's a user mindset thing. It doesn't make much sense to have a post about war and an NSFW post below it.

You've described twitter tho lol
Twitter/Instagram sort of work cos it's like you haven't commited to a goon app (is onlyfans even an app?). Your normal feed is peppered with nsfw (generally speaking) rather than dedicated to it.
Anyway ¯\_(ツ)_/¯ it's an interesting experiment at the very least. I'm sure it'll be made :) good luck to em
