I went and scrolled facebook recently and it is absolutely crazy. You get some ads, sure, and a few things that real people posted, but like half of what is on there feels like some kind of shady psychological experiment.
It's like a whole spectrum of flavors of ultra-processed engagement bait. Much of it is made to look like normal people posting normal things, just with a "follow" next to the name and 5,000 replies from kind old people trapped in a rabbit hole they don't even know exists.
