Wikipedia bans Congressional IP addresses

In response to revelations that Congressional staffers were editing entries to make their bosses look better and the opposition look worse, the folks at Wikipedia have cracked down on and banned them from being able to edit entries on the site.

I suppose this sort of thing is likely to be an issue with an open source encyclopedia, and it's probably more widespread than people know. Currently, there isn't a lot in place to stop individuals or private companies from trying to whitewash their entries as well. Currently, if an article is slanted, people can dispute the article's integrity and a process to resolve the dispute takes place.
