A mere 0.1% of users share 80% of fake news. Twelve accounts – known as the “disinformation dozen” – created most of the vaccine misinformation on Facebook during the pandemic. These few hyperactive users produced enough content to create the false perceptions that many people were vaccine hesitant.

So, this is super anecdotal, but through the father of a friend I learned about a guy who was just downright a walking stereotype in that regard. Said father is a rather conservative guy (ex-cop, actually), got lucky and rather rich, and he lived in a suburban village here in Germany. Said neighbour, as described by him: Also an ex-cop, old acquaintance, wife and kids left him because he was violent, living financially comfortably in a large house in that suburban German village on his own, but miserable. And he, unironically, sent said father of my friend far-right propaganda articles, images, messages just... all day long. Every 10 minutes or so. Presumably as mass messages to about anyone who still had a semblance of contact with him. Anecdotal, hearsay with 2 degrees of separation, but - it was the first time I realised those people existed as actual people just casually living their lives around us all.
