Throughout mid-2008, a number of [[Wikipedia Review]] members joined [[Directory:Gregory J. Kohs|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 [[Directory:United States|United States]] Senators.  [http://spreadsheets.google.com/pub?key=psAWteTSyixEB98YcV-5VEw 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 [http://stats.grok.se/ 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%.
