I was getting a little sick of the quality of the stuff Facebook was showing me, so I started fresh. I deleted my account, added back all my friends... but I didn't join any groups or like any pages. Even the ones my friends invited me to.
Then, I started hiding and blocking anything that didn't come from one of my friends directly. That includes stuff they shared from pages or other friends of theirs. I also started managing the advertisers who had shared lists using any of my contact information (FB has a dashboard for that) and leaving 1-star reviews for all of them.
This had hilarious effects on Facebook itself. After about a year of this, sometimes the newsfeed couldn't find stuff to show me, and it even completely broke a few times. Group recommendations started to veer towards substance abuse recovery support (I assume many people create new accounts to join them anonymously). Facebook would insist on showing me stuff from pages or friends of friends even after I hid them, because it seems I had blocked so much stuff their filters were not working right anymore. Not that they actually care.
Of course, the fun I had breaking Facebook doesn't change the fact that this was a huge chore that I mostly kept doing out of spite and habit. When I realized I wasn't even using the platform to keep up with old friends anymore, I realized it was time to let go.
The only FB product I keep using is WhatsApp, and it's only because I failed at convincing my friends and family to move to Signal, Telegram or Discord. It has too much of a stronghold in my country.
