I’ll be real with you, it’s info that I read in passing and later lost because I keep fucking up and not saving my tabs. (My web browser on desk top has “close individual tab” and “close all tabs except this one” right next to each other, and I have at multiple times lost a few years of research because of a slip of the finger)

From my recollection it was on a Russian history site I was translating that mentioned their existence through out the life of the Soviet Union as forms of experiments in alternative organizations of societies on a micro level.
