@smays the term 'bot' is a bit loose for these mass propaganda / harrassment troll farm accounts - they're only partly automated, I think - but Gamergate veterans (eg Zoe Quinn of Crash Override), Trump watchers (eg Josh Marshall at Talking Points Memo) and now various US Intelligence types are pointing them out.
Giveaways: poor English, tweet on Moscow time, massive no. of posts, themes track official Russian disinfo (eg, RT or Sputnik news), also track with Brietbart, Zero Hedge, Alex Jones.
