These are the same techniques used by the Soviets to control decent. Pretty scary.
"Cass Sunstein, Administrator of the White House Office of Information and Regulatory Affairs in the Obama administration, co-authored a paper in 2008 with Adrian Vermeule titled ““Conspiracy Theories”, about the risks and possible government responses to conspiracy theories such as theories about the attacks on September 11th. The paper refers, several times to groups that promote the view that the US government was responsible or complicit with the attacks as “extremist groups”. Together they propose that “the best response consists in cognitive infiltration of extremist groups” 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”."
Facebook managers have decided to upgrade the “Groups” feature, not to be confused with Pages or Profiles. However not all groups will be upgraded to the new design.
