Of course I am exaggerating. But IMO people vastly underestimate how similar their own behaviour is to other people. Meaning, if Facebook "knows" me since 12 years (!) it can very precisely categorize me into a group of people. And those other people do not leave Facebook but feed it more information.
Even worse are the socially slip-streamed ones that started as a Sponsored post in a friend's news feed that they found funny/interesting/whatever and re-shared. Once reshared it loses even that gray, barely there "Sponsored" tag and has "grown up into a real boy" in the news feed.
A lot of the mind games in the last election cycle happened because of that (target ads to people susceptible to reshare them and watch them go viral for relatively cheap). Facebook has said they may try to crack down on that sort of thing, but slip-streaming ads is where they make their most money and they don't have enough financial incentive to really fix that.
It almost makes me jealous of all the data they have.
