I took a similar approach, but I need messenger and I often use marketplace.

So I unfollowed every human in my feed. I doubt I've got them all yet, a few months in, but some old friends the algorithm just never shows.

I replaced it with some groups about hobbies like fishing and motorcycling, but I'm finding even that is just all arguments, gear reviews, spam, and rule reminders.

So I'm gonna phase that out, too.

Anyway it definitely keeps me from scrolling. If there's any posts I want to see, I'll never know it and I expect I'll be the better for it.
