MITRE research
i mentioned the Mitre Corp over a year ago on a bread - i lived in the area for many years, was born and raised there, and because of my father's line of work I knew a fair bit about the evil entity that is Mitre, so i explored their site to see what they were up to. one thing i discovered on their site is the Happiness Index, which i mentioned in my post then. it's a Mitre grant-sponsored creation by three Univ. of Vermont people that samples gives an ongoing plot of "happiness" based on the frequency of keyword usage on twitter. Mitre doesn't give a fuck about happiness - they put money into this because of its potential to shape social media quickly.
the Happiness Index could be flipped in a moment to favor (and to ban) any ideology - it would easily be able to function as a means of realtime banning and shadow-banning, by sifting for keywords like "Trump" and "patriot" and, with a few extra lines of code, putting holds on accounts with a certain threshhold of keywords. they get to use an API for twitter posts, which they can then drill down to your social network and who's responding to you based on that original terminology.
i believe the three guys who created the Happiness Index are the people Jack meant when he said he'd call on his "three friends" to increase the shadow-banning and full-on banning. they went on to incorporate as Quokka Labs. The three of them are total sjw leftards (read their bios and twitter accounts). The Univ of Vermont computer labs has done a fuckton of projects that favor the left/socialists, but they've redone their website and concealed those. i may still have those pages on my old laptop
my evidence is admittedly not rock-solid, but it's not like there's going to be hard proof of this. but i'm willing to bet an amount of money i don't even have that i'm right about this, and that these are the guys behind the logistics of the twitter (and probably fb and instagram) bans. Mitre was by its own admission looking for ways to direct social media in the way it wanted to go, and quickly.
