This was announced by Censor.NET Chief Editor Yurii Butusov in his blog.
He notes that on the basis of court's ruling, the Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications banned Censor.NET in the Russian Federation. Such indignation of the Russian side, was in particular provoked by articles and publications about Putin: Vasyl Rybnikov's article about Vladimir Putin "Vova the restorer," jokes about Putin by Oleh Grin, and news "Mariupol residents: Putin is murderer of Vostochnyi [MLRS Grad-hit city district - ed.]," "Putin - murderer," - Ukrainians come at Netherlands Embassy."
The text of the ruling is available here (in Russian).
"Well, it's honor for us to be banned in a neo-Soviet "empire." It means we are doing a right cause. And the Russians will shortly start using anonymizers and VPN servers, so the Kremlin has poor chances of blocking the Internet," Butusov commented on the ruling.
