Earlier quoted context omitted.
No joke, I use Facebook every year or so to access the marketplace and at the time my feed was roughly half rage-bait, and the other half being what I can only describe as AI-generated almost-pornography. Both had thousands of what looked like genuinely real interactions per post, mostly from developing country users.
I'm loathe to defend Facebook but most people's experience is not yours. The algorithm pushes content you're most likely to engage with, in your case it has nothing to go on so probably pushes whatever causes the most reaction in general.
This timeline sucks.
