Since 2002, Sanger has been critical of Wikipedia's accuracy.[44] In December 2004, he wrote an article for the website Kuro5hin, in which he stated Wikipedia is not perceived as credible among librarians, teachers, and academics because it does not have a formal review process and is "anti-elitist".[45][46] Shortly after the launch of Citizendium, Sanger again criticized Wikipedia, stating it was "broken beyond repair" and had a range of problems "from serious management problems, to an often dysfunctional community, to frequently unreliable content, and to a whole series of scandals".[2] In September 2009, Sanger said he distanced himself from Wikipedia partly because; "I thought that the project would never have the amount of credibility it could have if it were not somehow more open and welcoming to experts ... The other problem was the community had essentially been taken over by trolls to a great extent. That was a real problem, and Jimmy Wales absolutely refused to do anything about it."
