Also, Russia, Ukraine and Belarus are the motherlands for hackers of all sorts, we have bots who post pro-Kremlin comments on social networks too.
My favorite example is this one: http://apikabu.ru/img_n/2012-02_4/5c7.jpg
The description says "DO NOT POST COMMENTS, who post a comment will be banned", and underneath it different bot accounts post messages about how bad it is to join protests and American government controls the opposition, nonsense like that.
Don't worry about hacker news or other sites like this one — the government thinks people don't know English to be on these sites. Partially it's true, though, most people still are unaware of real situation because they don't have internet connection (they get news from television, as here it's called "ZomboTV" ("Зомбоящик"), you guys have it too, imagine if all the channels were like CNN) and most of their time they spend on trying to survive in this economic situation (google "dollar to ruble"), they have no time to protest or find true information about their government and "president" (a mafioso Putin, google "dacha consumer cooperative Ozero")
