[Ed. – Too much good pravda.]
It appears that an internet user from within the All-Russia State Television and Radio Broadcasting Company (VGTRK) changed a Russian language version of a page listing civil aviation accidents to say that “The plane [flight MH17] was shot down by Ukrainian soldiers”.
That edit replaced text – written just an hour earlier – which said MH17 had been shot down “by terrorists of the self-proclaimed Donetsk People’s Republic with Buk system missiles, which the terrorists received from the Russian Federation.”
All edits to Wikipedia are permanently logged, with the username and IP address being stored along with the changes they have made.
An automated Twitter bot called congress-edits was created to monitor for changes made from US Congress computers and immediately tweet them. The source code powering that project was released to the public, allowing the creation of RUGovEdits which performs a similar role in Russia.
A tweet today from that account, translated into English, says: “Wikipedia article List of aircraft accidents in civil aviation has been edited by RTR [another name for VGTRK]”.
