Pentagon and others manipulate social media to shape opinion on Security State.

1. One poster over at www.schneier.com fit this bill.

Bruce Schneier is a computer security expert who got interested in real-world security systems after 9/11. He is also a board member of the Electronic Frontier Foundation. His book: "Beyond Fear -- Thinking Sensibly about Security" was a must read about all the things that the security state that Bush created did for no purpose other than to "appear" to be in control. I believe he coined the term "Security Theater" to explain these things -- a term that now had wide usage.

Anyway, he had a long-time poster in his blog's comments section, "Skeptical," who was 100% the government party line on all electronic issues. Skeptical was usually VERY quick to post (no more than a few hours consistently and minutes sometimes) and always had long talking points prepared. He especially got worked up about all things Snowden and arguments about how government backdoors in consumer electronics actually INCREASE risks for the average citizen.

I (and many others who read that blog) could never shake the feeling this poster was an example of the social media operation you describe.

He eventually disappeared in late 2014 (https://www.schneier.com/blog/archives/2014/11/economic_failur.html), many regular posters hypothesized that it was because his arguments usually drew quick and thorough rebuttals that actually made the governments' position on many computer issues look worse.
