I just use FB as a “fan page” for selling books. I don’t put any personal data on it beyond my region being north FL.
One of my goals with writing “What I saw at the coup” was to put the danger of Social Network Analysis being used as a purge tool out into the open. The KGB, Gestapo, Stasi etc never had such dangerous tools. They had to purge tens of thousands to be sure of getting a few enemies.
SNA will allow future tyrants to dial the purges down to an acceptable and almost unnoticable level. Even the selective use of deniable means such as “Breitbart’s Syndrome” could be an option.
You and I remember how a few Freepers like us after 9/11 pulled the covers aside to reveal how the Islamos had training camps by Fresno, in Oregon and in the Virgina/DC area.
We did that with our limited computers and search platforms.
One can only imagine Data Mining the SNA’s with powerful computers and search programs.
Kudos to you for addressing this reality in your book and here.
