I think there are putinbots on reddit and maybe even HackerNews. I've had situations where I would see a ridiculously revisionist pro-Russian comment with 10+ points on reddit, then I would reply with a totally reasonable comment asking for sources, and I would get downvoted 10+ times within a very short period of time (~5 minutes). Then I would come back to it a couple hours later and the initial comment that I replied to would be -10 points and my comment would be +10. What I am guessing is happening is the initial post is made by a putinbot and upvoted by other putinbots. When I make my comment asking for sources, they all downvote me. Then after sometime the reddit community gets a chance to vote on the comments and they adjust them to the actual score they should be. Obviously this doesn't confirm the existence of these bots, but it is very suspect.
