First draft:
Tacit Approval (legal term: silent agreement) This is a technique where operators will try to convince the user population to ignore, or not respond to bad information or false assertions. It's worth noting that the ID filtering mechanism of the boards (which currently can't be disabled without a code change from the site admin) is used as a weapon of sorts in this tactic: Filtering with software prevents anons from defending against seeding bad information and astroturfing consensus. This is ''why'' the operators push so hard to condition anons into filtering material they disagree with.
