The way it’s set up is they have the obvious trolls and then the ones with cover, those who pose carefully as normal posters. The effect is that the obvious ones take the heat off the ones who put effort into sounding legit. This second group then goes about their mission of seeding the forum with false information, especially stuff like Jerome Corsi is “less than believable” and Ted Malloch “enhances his resume.”
One of the most basic principles of propaganda is to establish the propagandists as trustworthy and credible.
Another key aspect of their game is to stage arguments between two or more members of their paid fake posters club. For example, the obvious trolls will bait the deep cover trolls who then respond with a phony rampage. It’s all about setting up their positions.
