In Russia, "extremism" is being against Putin or the war. For example, posting photo of Alexey Navalny is "displaying extremism symbol". Also, there are people charged with extremism for posting a link to instagram/facebook domains (Meta is an extremist organization).
Also "facilitation of exam cheating" is the most stupid accusation. Why they cannot keep exam question in secret? Also why they do not shutdown scammer call centers which scam Westerners? So they want Telegram to be blocked but scammer call center to continue operating?
