No, it gets dumped on pretty much everybody.

My Insta consists of travel and food pictures, and the people I follow are friends IRL and a very few travel/food influencers. So my feed consists of friends, travel/food content, dirty jokes thanks to my buddy who keeps sending them, and an ever increasing proportion of ads.

But both my "suggested reels" and the search view are exactly what the OP was complaining about: a non-stop parade of thirst traps by "content creators" pitching their OnlyFans accounts.
