Oh, this is sweet:
On November 17th, 2005, an anonymous Wikipedia user deleted 15 paragraphs from an article on e-voting machine-vendor Diebold, excising an entire section critical of the company’s machines. While anonymous, such changes typically leave behind digital fingerprints offering hints about the contributor, such as the location of the computer used to make the edits.
In this case, the changes came from an IP address reserved for the corporate offices of Diebold itself. And it is far from an isolated case. A new data-mining service launched Monday traces millions of Wikipedia entries to their corporate sources, and for the first time puts comprehensive data behind longstanding suspicions of manipulation, which until now have surfaced only piecemeal in investigations of specific allegations.
Wikipedia Scanner — the brainchild of Cal Tech computation and neural-systems graduate student Virgil Griffith — offers users a searchable database that ties millions of anonymous Wikipedia edits to organizations where those edits apparently originated, by cross-referencing the edits with data on who owns the associated block of internet IP addresses.
Other Wikipedia edits have been made from IPs owned by the CIA, Microsoft, Wal Mart, and Fox News. Someone from the latter changed this:
The lawsuit focused a great deal of media attention upon Franken’s book and greatly enhanced its sales. Reflecting later on the lawsuit during an interview on the [[National Public Radio]] program ”[[Fresh Air]]” on [[September 3]], [[2003]], Franken said that Fox’s case against him was “literally laughed out of court” and that “wholly (holy) without merit” is a good characterization of Fox News itself.
