Why would the government even bother to do that? It flatters the conspiracy theorist to believe that their internet postings could somehow be a threat to the dark forces against which they rail. I think what's happening is that someone disagrees - admittedly quite angrily - about what other people are posting. How much posting history does a member need before they can go against the prevailing consensus?

They go on to propose that, ”the best response consists in cognitive infiltration of extremist groups”,[19] where they suggest, among other tactics, ”Government agents (and their allies) might enter chat rooms, online social networks, or even real-space groups and attempt to undermine percolating conspiracy theories by raising doubts about their factual premises, causal logic or implications for political action.”[19]

Shortly after taking office on January 20, 2009 President Obama appointed Harvard law professor (and personal friend) Cass Sunstein to the post of administrator of the White House Office of Information and Regulatory Affairs. In June 2009 Sunstein published an essay in The Journal of Political Philosophy entitled “Conspiracy Theories: Causes and Cures,” in which he provided an “analysis” of conspiracy theories, viewing them, as his title indicated, as “caused” by psychological conditions and requiring “cures”, i.e., elimination. The article led to an outcry by civil libertarians of all political stripes, who especially singled out for protest Sunstein’s call for covert “cognitive infiltration” by government agents of organizations the government deems “conspiracist”.
