It’s not that at all. I keep tabs on several far-flung friends and relatives on FB. Zero spam. TBF, I make it a point to click on ads for things I don’t need but don’t mind seeing (rockets, 3D printers, vocal jazz stuff). Of course, I’m on IPv4 with my whole household, so if I search for hiking shoes, everyone in the house gets FB ads for hiking shoes. I got a bunch of ads for Merino Wool outerwear in mid December. My wife was kind enough to get me several base layers for Christmas. There is no good and bad, just poor internet management and hygiene (IMHO).
