I found that LinkedIn is great at this, too. I regularly see posts from contacts in my feed that are three weeks old and that I've never seen before.
edit: LinkedIn will also shadowban your posts if they contain words from a blacklist. Just this morning a contact complained about that. He was very happy about being engaged as a speaker and wrote in a post "Das ist schon sehr geil [...]". While "geil" means "horny", especially younger Germans use that word without the sexual connotation but as a replacement for "great". His post reached only a few dozen people instead of hundreds, as normally.
edit: "Das ist schon sehr geil" could be translated as "That's really great indeed"
Most people won’t ever have any real idea of what, or how much, they are being prevented from seeing. You also can’t use these platforms to point out their own censorship. I imagine most people have no real idea that most of their feeds on all the platforms they use are heavily censored, or could be totally censored in an emergency.
This situation is a ticking time bomb. I hope it doesn’t go off this year.
Or few weeks ago, lasted maybe 2 weeks, they've run some experiment/had bug in their over-buggy web page, since literally nothing moved in the feed. I saw the same posts as week ago, nothing new, in same order.
Also, when covid started, the feed just exploded with ad posts, which were rare for me before.
FB is amoral, abhorrent company with consistently crappy buggy product, that I hope will disappear over time. I'm not naive enough to think their replacement will be better.
People don’t spend the whole day scrolling, and Facebook knows this. They know exactly how far down each and every person scrolls.
This means they know exactly how much other content they need to “promote” to totally and effectively censor content they don’t wish people to see.
Algorithmic “timelines” (which aren’t timelines at all) are nothing more than censorship: a remote organization deciding what you’re allowed to read.
Confused players look at each other, “Uh, you mean about the Facebook thing? Why would you do that? We would have been fine just betting a dollar or whatever...”
Then everyone folds and you collect the ante.
They are constantly mucking with what's presented. Not long ago, my feed was pretty well distributed across my few hundred friends. As of maybe a few months ago, it's the same circle of ~20 similar-minded friends. At the expense even of showing me the same post I've seen for 5 days straight.
The people that engage my posts are always a cohort, with 90% overlap with my feed.
I swear there are also things which boost/nerf exposure based on sentiment analysis.
I'm an infrequent user cause it's kinda addicting (infinite scroll) and also this echo chamber trash.
