The incident raised questions about the reliability of Wikipedia and other websites with user-generated content that lack the legal accountability of traditional newspapers and published materials.[3] In a December 13, 2005, interview,[4] co-founder Jimmy Wales expressed his support for Wikipedia policy allowing articles to be edited by unregistered users, but announced plans to roll back their article creation privileges as part of a vandalism-control strategy.[4] The incident ultimately led Wikipedia to introduce stricter referencing requirements for biographies of living people.
