Wikipedia Vandalism Study

Throughout mid-2008, a number of Wikipedia Review members joined Gregory Kohs in a project to methodically enumerate one calendar quarter’s worth (4Q 2007) of edit data underlying the 100 Wikipedia articles about the (then) current United States Senators. What they found was alarming at times. While most vandalized edits were brief in duration and clearly juvenile in content, a substantial portion of edits were plainly intended to be hurtful and defamatory against the Senators — and they lasted for not just minutes, but hours, days, even weeks at a time.

Using the Wikipedia page traffic tool, they attempted to interpolate the number of “page views” that each Senator’s article likely witnessed during the damaged edit. The damaged edit that saw the greatest number of page views before correction regarded Senator John McCain: "McCain was born in Florida in the then American-controlled Panama Canal Zone", which lasted for over 3 days, under about 93,000 views where nobody noticed or bothered to correct this obvious error.

In all, the median duration of a damaged edit was 6 minutes, but the mean duration was 1,440 minutes (exactly 24 hours). These 100 articles were viewed approximately 12.8 million times in the fourth quarter of 2007. Over 378,000 of those views could be considered “damaged”, yielding a 2.96% rate of damaged views. There were about 13.2 million article-minutes during the quarter, and over 901,000 of those article-minutes were in a damaged state — 6.80%.

This is not an issue of “damaged” versus “acceptable” rates. Rather, it is an issue that the Wikimedia Foundation allows anonymous editors to append the article about Hillary Clinton with “hillary needs to die and chop of her penis”; or to modify the article about Bob Menendez to say “Menendez and Jacobsen have since divorced because he was cheating on her”; all without any meaningful effort to change the parameters of editing to disallow this kind of drive-by hatred and libel.

Other examples

• For 3399 minutes, the Wikipedia article about Senator Harry Reid of Nevada said that he was "married to his right hand". About 1383 people saw the article like this.
• The article on British journalist Tom Utley was vandalised by an edit (since deleted entirely from the Wiki database) claiming "He is the proud father of 4 sons. One of them is propa belta at smokin tac. The other is currently havin an affair with Mylene "Sideboob" funbags Klass. Raker. One other is MDMAzin. and the other i dont have any scoop on but there are rumours he was caught fornicating with a dead brown bear that was actually black. " made on 11 July 2007 and which was not spotted until 23 July 2007. Utley wrote about this commenting "I notice that Wikipedia's article on itself is marked with a padlock, meaning it's protected from interference by you or me - which doesn't say much for its managers' faith in the emergence of truth through absolute freedom".
