The Department of Health has been banned from Wikipedia for making too many edits - 1500 Wikipedia amends between 22 August 2005 and 3 August 2007.

"Wikipedia has blocked the Department's IP address for creating or amending entries", Labour minister of state for the Department of Health, Ben Bradshaw revealed.

"Information on the Wikipedia site indicates that this has occurred because it has identified the IP address as being shared by many users."

"Since the IP address has been blocked, staff wishing to create or edit entries from departmental computers must create a user account with Wikipedia. Wikipedia will not release details of user accounts."

The Department of Health denies staff were asked to edit the site and has told PC Pro. "The Department does not contribute to Wikipedia and it is not part of the Department's communication or information strategy."
