Russia seems to have a conflicted relationship with Twitter and Internet censorship in general.
While trying to portray themselves as open and democratic, they clearly have a real problem with the radical openness of social media like Twitter.
Maxim Ksenzov, deputy head of Roscomnadzor (Russia’s censorship agency), said Twitter is a “global instrument for promoting political information” and that they could block Twitter or Facebook in minutes.
Prime Minister Dimitri Medvedev responded on his Facebook account, saying that state officials “sometimes need to turn on their brains” rather than "announcing in interviews the shutdown of social networks.” Which is not quite the same as saying that they would not do so.
The primary desire in Russia is for Twitter and all other social networks to open offices in Russia. That would smooth communications, but also provide leverage to push for censorship or access to data as needed.
