WikiScanner - Wikipedia, the free encyclopedia

WikiScanner (also known as Wikipedia Scanner) is a (former) publicly searchable database that linked millions of anonymous edits on the free online encyclopedia Wikipedia to the organizations where those edits apparently originated, by cross-referencing the edits with data on the owners of the associated block of IP addresses (WikiScanner did not investigate edits made under a username.) It was created by Virgil Griffith and released on August 14, 2007.[1][2] In his "WikiScanner FAQ" Griffith stated his belief that WikiScanner could help make Wikipedia more reliable for controversial topics.[3] Griffith also indicated that he had never been employed by the Wikimedia Foundation and said his work on WikiScanner was "100% noncommercial."[3]

As of April 8, 2013 (2013-04-08), attempts to run "WikiScanner Classic" from wikiscanner.virgil.gr returned to the WikiScanner home page, which identified itself as "WIKIWATCHER.COM"; and invoking "WikiScanner2 PreviewNew!" led to failure to load the page due to timeout.[4]

On December 21, 2012 a research group from Fondazione Bruno Kessler (it) released an open-source clone of WikiScanner called WikiWatchdog.[5]
