A Twitter bot that watches for anonymous Wikipedia edits from a range of Congressional IP addresses lit up with activity on Monday as somebody — we don’t know who — made unusual changes to 13 wide-ranging Wikipedia articles.

The article topics range from Choco Taco to the Russia Today journalist Abby Martin to the right-wing radio host Alex Jones. All were lightly altered to praise or denigrate the subject.

In at least one case, the Wikipedia entry for Crimea, the anonymous Congressional operative made a geopolitical clarification that fits the U.S./Ukraine viewpoint on Russia’s conflict with Ukraine.

Crimea Wikipedia article edited anonymously by US House of Representatives http://t.co/Lfb0rEbVUh — congress-edits (@congressedits) July 14, 2014

The Crimea listing originally looked like this:

Sovereignty and control of the peninsula became the subject of the ongoing [[2014 Crimean crisis]], a territorial dispute between Russia and Ukraine.

But the anonymous Wikipedia user thought this was a more accurate depiction of the occupied Crimean peninsula:

Although the region is a ''de jure'' part of Ukraine, control of the peninsula became the subject of the ongoing [[2014 Crimean crisis]], when the peninsula was illegally annexed by Russia.

A few moments after making those changes, another user reverted them back.

But the Congressional editor didn't stop there.

Of Alex Jones: “Following his appearances on Russia Today, there were allegations that he was a disinformation agent with ties to the Kremlin.”

Of Abby Martin: “Abigail Suzanne ‘Abby’ Martin is a Russian propagandist…”

Of David Icke: "He is also a disinformation agent funded by the [[Pleiadians]]."

Of Lyndon LaRouche: "He is also a disinformation agent funded by the Kremlin."

And of the LaRouche movement's ideas: "which are heavily influenced by [[Trotskyism]]."

The user also made a few entertaining trivial edits, such as adding Bon Jovi to the list of musicians that have appeared on It's Always Sunny in Philadelphia, and adding key facts on Choco Tacos — which were allegedly a favorite snack of former House Speaker Sam Rayburn.

The address, 143.231.249.138, is a static IP address that is assigned to the U.S. House of Representatives. It’s been caught red-handed before, too.

In 2009, a user at the IP address was caught editing U.S. Rep. Devin Nunes’s Wikipedia listing, calling him a Nazi and add highly-suspect comments to articles related to abortion facilities.
