From a friend:

First, we know that Russia presently, in theory, has a very restrictive speech code against anything “nationalist” or “extremist”. Called Article 282, it’s seen people face prison sentences for very mild statements like “Chechnya [source of Putin’s private army] is a drain on the national treasury and should be made independent”, as well as racial nationalism (or literally just noticing race—as one person found out, mentioning sub-races and super-races in the sense of concentric circles and descent was interpreted as implying superiority and inferiority, and therefore punishable)
