So the DUMB thing about the Instagram feed is that they will show you things that those you're following will look at, especially if it has no idea your preferences.

I initially got Instagram to follow a few brands that I follow, just to get updates on them, and also a few of my friends. I seldom post stuff, and I almost never like stuff because that wasn't what I got Instagram for.

For the longest time, scantily clad women kept turning up in my feed even though I don't look at such stuff, and even after repeatedly clicking the "do not show me similar stuff" button. My gf was also semi-pissed when she saw my feed.

Eventually she started working at Meta and found out how their algorithms work and told me about them (see first sentence).

Recently, I started to like some watch photos (got into modding Seiko watches) and now my feed is nothing but watches.
