If you think this is interesting, see what happens when you try and edit the page of Susan Gerbic; the leader of the Guerilla Skeptics. She runs a gang of over 150 Wikipedia members who have taken over 1500+ articles. They are like the deletionist described in the article, but operate as an open conspiracy advancing an atheist-materialist point of view. They actively recruit new members, run them through extensive training about the Wikipedia ecosystem and how to dominate it as a team.
