I tried copy/pasta but the article is long, difficult to to embed all images/links of which there are many.
Here is a TL;DR:
Among the core self-identified purposes of JTRIG are two tactics: (1) to inject all sorts of false material onto the internet in order to destroy the reputation of its targets; and (2) to use social sciences and other techniques to manipulate online discourse and activism to generate outcomes it considers desirable.
Mind blowing article with so many implications. Unfortunately this gives more credibility to people calling "shill" with everyone they disagree with. But it turns out that there are such agents actively manipulating opinions in online forums. The slides he shows even mentions some of their tactics such as using: confirmation bias, disinfo, slander, anchoring, priming, social penetration theory, attention control, etc.
