The new bot @Congressedits, which tweets anonymous Wikipedia edits made from Capitol Hill, discovered one of its most substantial revisions on Tuesday. The program listens for Wikipedia changes stemming from Congressional IP address ranges, and it auto-tweeted about an alteration to the page for Navi Pillay, the United Nation's High Commissioner on Human Rights.

The 33-word revision to the page for Pillay added that the commissioner has received "criticism for reffering (sic) to Edward Snowden, the American traitor who defected to Russia, as a 'Human Rights Defender' and saying that he should not face trial for his crimes." The month before, Pillay made headlines when she said Snowden "should be seen as a human rights defender," and "We owe a great deal to him for revealing this kind of information."

The edit comes after Wikipedia recently handed out both 10-day and single-day bans on edits from Capitol Hill. The move hoped to deter edits like the one above for Pillay or for a recent edit on the entry for Web outlet Mediaite. Not long after Mediaite wrote a story about @congressedits , Mediaite's Wikipedia entry was changed by someone in the House, calling the site a "sexist transphobic news and opinion blog" that "automatically assumes that someone is male without any evidence." (That change was cited by the Wikipedia admin who imposed the ban, according to The Hill .)

These Wikipedia entry switcheroos may not have been publicized at all if not for @congressedits. The Twitter bot was started last month to take advantage of a program developed by Ed Summers, an open source Web developer. Summers said he got the idea from a UK Twitter account that did the same thing for Parliament, and already the @congressedits handle has more than 26,000 followers.

On Parliament's side of the pond

In Europe, Wikipedia is focusing on entire article deletions rather than edits. Jimmy Wales, the Wikipedia founder, is seething over Europe's "Right to be Forgotten" ruling, saying it has claimed the online encyclopedia's first page and is "completely insane and needs to be fixed." Wales believes the "Right to be Forgotten" ruling not only threatens the Internet's free flow of information, but it provides an even more Draconian method of altering Wikipedia—in this instance, deleting pages altogether.

The European Union’s highest court, the European Court of Justice, ruled in May that Internet search engines like Google must erase links related to webpages in certain cases where the information contained is deemed "inadequate" or "irrelevant." Google has received tens of thousands of demands to remove links, and it's in the process of deleting them from its European search results.

At least one of those links is a Wikipedia page, according to Wales. So far, he's been mum on which Wikipedia page is set for removal. But Wikipedia is holding a news conference Wednesday in London, and it's expected to announce what page, or pages, are being removed.
