On 18 July, someone in the Russian government edited Wikipedia. They opened up an article titled "List of aircraft accidents in civil aviation" and scrolled down to the entry about MH17, the Malaysia Airlines flight that had been shot down just the day before. At the time, the article blamed terrorists from Russia. The government official deleted that passage, instead pointing the finger at the Ukrainian military for the accident. How do we know this? A Twitter bot caught him in the act.
