Your last two paragraphs sound an awful lot like the book 1984. If you haven’t read it, I recommend you check it out.
"You can fool some of the people all the time," as said by Unknown -- probably not Lincoln, but one of the things continually misattributed to him, in an earlier style of meme misinformation. It is ironic that people thought that the internet would purge misinformation (by making sources easier to check) but instead it has made it worse, by bypassing expertise, analysis and references altogether.
1984 isn't really about tribal groupings using computerised social credit systems, but I take your point. From the authoritarian POV, China already has nascent systems to score each citizen's thought correctness factor.
