Then the algorithm is very broken for me. I post extremely benign and even somewhat boring things for my friends and family, scroll through the Marketplace scams occasionally, literally never watch Reels, and still--to this day--Facebook thinks I want to watch videos of teenage girls in loose-fitting bikinis jumping on trampolines.

My conclusion is not that the algorithm shows you things it THINKS you will engage with, but rather things they WANT you to engage with because it makes them money somehow.
