Is FB optimized to kill my time?

If you have been using FB pretty frequently for the past few years, have you recently acquired a FB friend who you’ve never met in real life, but who suddently posts the exact content you love?? (Except just a few posts that are totally weird.)

Well, I think that “friend” is not a real person, and is actually a result of an ML network that was trained on my FB data. FB knows I’m more likely to pay attention to posts from my “friends”, instead of ads, so it created bot friends.

(If you don’t have a FB friend like that, well, may be it’s just just a fluke.)
