I have my Facebook feed curated enough that it shows me reels I like (landslides, dance-offs, kids or animals doing cute things - nothing salacious). Of course, AI crap filters in, but a majority are still good.

Even the sponsored posts are very often interesting summaries of historical events or scientific wonders. They're AI most of the time, which goes on and on. So I read the first part and then go to wikipedia if I'm more interested.

I'm also in a bunch of private groups that are spam-free. Some travel-related groups have turned out to be invaluable resources.

So it does work if you train it on what you like.
