I looked at a few of them because they had interesting titles, but the ones I saw didn’t say anything worthwhile. So I consider them to be another form of advertising on Facebook since people who make them get paid for the amount of views they get.
I use that extension “fluff buster purity” and I am able to block reels. But Facebook has been doing some weird stuff lately. I had to block anything with “suggested for you” in it as it seems that is ALL I was being shown.
