He re-tweets an epic fuckton of stuff, and that makes up the bulk of his tweets. Sure, he goes off on long, whiny, multi-tweet threads on occasion, but at least 85% of his Twitter feed is other people's material, pretty much shared into the void because he has scarcely any friends.
It's as if he has no idea that he can simply "like" a tweet without sharing it, and given that most of the tweets he shares aren't all that interesting, maybe that's actually the case. He's proven himself remarkably stupid about very basic things over and over again, so why not this one?
