Thanks to Virgil Griffith, a Cal Tech grad student, anyone can now see how companies are editing their Wikipedia entries on the site Wikiscanner. This is possible because each edit is tracked by IP address, even those that originate in corporate offices.
In the past someone from Walmart has edited Wikipedia to put a positive spin on their employment practices. Someone at ExxonMobil did the same with an entry on the 1989 Exxon Valdez oil spill. An edit tracked from BustBuy changed a rivals name to Circuit “Noob” City. MySpace and other companies have completely deleted criticism.
They may have been trying to be proactive in cleaning up their online image, but ethics is doing the right thing when no one is looking. They must have had some inkling of the dubious nature of putting spin on an a public encyclopedia. We may never know who is guilty and how high in the organization these people were, but I think the good employees will refrain from using Wikipedia as a PR tool in the future.
