Rumor: Russian Gov't Editing Wikipedia on Flight MH 17
Russian Wikipedia page for the flight MH17
A Tweeter bot monitoring any edits made to Wikipedia from Russian gov't IP addresses
Nothing is definite but it's certainly obvious that Russian gov't is drifted into removing some pieces of info inconvenient to it from Wikipedia, such as the probable fact that it provided separatists with missiles that took down the commercial airliner.
It was detected by a Tweeter bot monitoring edits to Wikipedia made from Russian gov't IP addresses. US president Barack Obama mentioned that the tragedy was likely done by the separatists and added that without sophisticated weapons they couldn't be able to down the airliner. If it were true, it could be the most embarrassing Wikipedia updates ever in history.
