Roskomnadzor blocked the forum of math training Art Of Problem Solving, trying to restrict access to Telegram. Facebook user Sergey Markelov drew attention to this .
In this forum, I have never seen extremist criticism of Putin or the proselytism of Jehovah’s Witnesses (an organization banned in the Russian Federation). But there are many discussions of geometry, inequalities, polynomials, and so on.
Information about the blocking does not appear when the Art Of Problem Solving website is opened, but its IP address (220.127.116.11) is contained in the registry of the prohibited sites of Roskomnadzor – it was submitted there on January 15. The reason is the decision of the Tagansky District Court of Moscow to block Telegram in Russia.
More than one and a half million users visit Art Of Problem Solving monthly, according to SimilarWeb statistics . The main audience of the site is residents of the USA and Canada.
