FB used to have granular privacy controls and no "feed" -- you wrote on someone's wall, they wrote on yours, and people had to actively click on your profile to see the messages rather than have them thrust front and center.
FB abandoned that commitment to privacy and has suffered as a result.

I have a throwaway profile with no friends that follow now pages. In the absence of anything else, Facebook has somehow decided I would most like to see anti trans nonsense, flat earth conspiracy theories and child sexual abuse material.
(They don't remove the latter if you report it, of course.)
