US Department of Justice banned from Wikipedia
Found on The Register on Monday, 28 April 2008
Wikipedia has temporarily blocked edits from the US Department of Justice after someone inside the government agency tried to erase references to a particularly-controversial Wiki-scandal.
The DoJ did not respond to our requests for comment. But odds are, the edits were made by a single individual acting independently. Wikipedia's ban on the department's IP is due to be lifted today.
Political warfare on Wikipedia. Probably just one of the rare cases where it was noticed.
