But after a few years or so of constant nonsense, you become adapted to the addiction and just ignore everything on it. Atleast thats what happened to me.
I went from constantly checking twitter to deleting my account and just going to the feed of one or two people once a day to keep informed.
I now laugh at how worked up everyone gets, and all the play acting and rival factions involved. Its almost like an iq test, where you pass if you dont play the game.
The problem is a lot of people are staying indoors right now with nothing to do and are discovering twitter/reddit for the first time.
Imagine a person not only new to social media, but new to the internet as a whole with no bs filters built in. He/she would be such a mark.
The real herd immunity is people understanding over time how emotionally manipulative social media is and learning to ignore it like we do 99% of advertisements.
Don't forget YouTube. My mother in law started with YouTube videos on Bible studies in her native language and somehow got spun into some kind of conspiracy theory black hole. We worked to talk her down from the more crazy stuff (apocalypse predictions, Qanon, etc) but it's been years and she still watches her YouTube "news" on the daily so she can keep "informed"
