Detecting and preventing hoaxes in wikis

This page is emerging from a lengthy discussion on Breaching Experiments dealing with possibilities of research in the wiki environment. While planning an experiment aimed to infiltrate such a material might be highly controversial, there is a (hopefully) general agreement that preventing incorrect information to appear on any site (e.g. Wikiversity or Wikipedia) is useful.

List for now...
Here are some pages that might form the core of the page. Feel free to add/rework:
 * Reliability of Wikipedia
 * Criticism of Wikipedia
 * WikiScanner
 * Wikipedia biography controversy
 * USA Congressional staff edits to Wikipedia
 * List of topics characterized as pseudoscience
 * Wikipedia Unmasked
 * Wikipedia and the art of censorship
 * w:Wikipedia:Wikipedia Signpost/2010-03-08/News and notes - the problem is very real...
 * here is the full story - this is actually a case study from the "author" describing the whole process
 * Edward Owens - a case of a WP hoax designed by a group of students
