As native russian speaker, just in first lines directly i see posts have nothing to do with "farms".
For example, f9dded769bb2275fc6531c1b4d10cf05272c48806fbd73265ef318fac0a22962 is just reposting _in russian language_ russian (Kirov) city news. Most likely just some kind of automated bot, reposting newsfeeds from aggregator.
Can't see anything how it makes it "troll farm". And news even, seems, not biased, they reposted news from various websites pro and against government.
I feel i will be considered criminal, by default, just because i'm posting sometimes in russian language
