Anyone been able to get the click-bait girls out of your insta discover?

I've changed my preferences to only hobby stuff, cars, and 3d printing about a dozen times. Whenever I open my feed and see what I call "titty girls", I don't click on them, and push "not interested" anytime they pop up. Idk if it's just me, but it'll work for a few days, then it seems to default back to the "titty girls". My wife saw this too, I brought it up, she tried changing some things and watched the algorithm reset, so luckily there's no surprises there, but Holy cow, if i ever hop on insta in public, you'd think I was on pornhub or something. Unless I'm checking out instathots in my sleep, anyone have any suggestions outside of deleting the app? lol
