5) Anti-conspiratorial. They almost always have disdain for 'conspiracy theorists' and, usually, for those who in any way believe JFK was not killed by LHO. Ask yourself why, if they hold such disdain for conspiracy theorists, do they focus on defending a single topic discussed in a NG focusing on conspiracies? One might think they would either be trying to make fools of everyone on every topic, or simply ignore the group they hold in such disdain.Or, one might more rightly conclude they have an ulterior motive for their actions in going out of their way to focus as they do.
6) Artificial Emotions. An odd kind of 'artificial' emotionalism and an unusually thick skin -- an ability to persevere and persist even in the face of overwhelming criticism and unacceptance. This likely stems from intelligence community training that, no matter how condemning the evidence, deny everything, and never become emotionally involved or reactive. The net result for a disinfo artist is that emotions can seem artificial.
Most people, if responding in anger, for instance, will express their animosity throughout their rebuttal. But disinfo types usually have trouble maintaining the 'image' and are hot and cold with respect to pretended emotions and their usually more calm or unemotional communications style. It's just a job, and they often seem unable to 'act their role in character' as well in a communications medium as they might be able in a real face-to-face conversation/confrontation. You might have outright rage and indignation one moment, ho-hum the next, and more anger later -- an emotional yo-yo.
With respect to being thick-skinned, no amount of criticism will deter them from doing their job, and they will generally continue their old disinfo patterns without any adjustments to criticisms of how obvious it is that they play that game -- where a more rational individual who truly cares what others think might seek to improve their communications style, substance, and so forth, or simply give up.
7) Inconsistent. There is also a tendency to make mistakes which betray their true self/motives. This may stem from not really knowing their topic, or it may be somewhat 'freudian', so to speak, in that perhaps they really root for the side of truth deep within.
I have noted that often, they will simply cite contradictory information which neutralizes itself and the author. For instance, one such player claimed to be a Navy pilot, but blamed his poor communicating skills (spelling, grammar, incoherent style) on having only a grade-school education. I'm not aware of too many Navy pilots who don't have a college degree. Another claimed no knowledge of a particular topic/situation but later claimed first-hand knowledge of it.
8) Time Constant. Recently discovered, with respect to News Groups, is the response time factor. There are three ways this can be seen to work, especially when the government or other empowered player is involved in a cover up operation:
