I had that reaction as well, but consider: clickbait is such because it takes more work (emotional or logical) to reject it than an ad which is merely not relevant to you. Thus, your (and my) recall of ads is probably biased towards clickbait, and we overestimate its prevalence.

Not quite the same thing but some non-negligable percentage of ads I see on Facebook are outright scams which purport to be selling musical instruments at a 'markdown'. First guitars supposedly from the Sam Ash bankruptcy sales linking to an obvious fake site and more lately 'free' giveaways of high end Gibson acoustic guitars. When I've reported them I got the feedback that it didn't violate community standards, but my insta account got perma-banned when I posted the original of a song on youtube from 1928 on a thread which started with a cover from 30 years ago. That was considered spam.
