More Wikipedia Editing Greatness

Recently we told you about the Wikiscanner, and how it had uncovered several suspicious additions and edits by several businesses and government bodies.

The scanner has now uncovered a few other organizations abusing the online encyclopedia:
“Virgil Griffith's "Wikiscanner" points to Central Intelligence Agency computers as the sources of nearly 300 edits to subjects including Iran's president, the Argentine navy, and China's nuclear arsenal.

A CIA computer was the source of a whiny "Wahhhhh" inserted in a paragraph about Iranian President Mahmoud Ahmadinejad's plans for the office.”
In addition to the CIA, the Vatican has also been fingered in the removal of information that linked Sinn Fein leader Gerry Adams to a decades-old double murder.

What do you think of all the corporations and other organizations editing Wikipedia?  What, if anything, should be done to stop self-serving edits?
