My girlfriend also gets the same stuff over and over, most of it AI-generated garbage she's absolutely not interested in. No matter how often she selects "not interested", they always come back. Strangely, this started only recently on her account and mine is still comparatively okay. From what I've heard, it's much worse for US users.

One thing that amazes me is that Facebook thinks I'm interested in content I was interested in more than 25 years ago before Facebook even existed. It's mysterious.

Once I looked at the comments for a disgusting AI-generated tiny house picture to see if anyone else knew it was AI-generated and then all it showed me were more disgusting AI-generated tiny house pictures no matter how many times I tried to block it.
