Is it more likely that hundreds/thousands of Russian citizens are utterly delusional to the point of insanity, all the while being perfectly Internet savvy, or that there are propaganda firms working for Putin to control the Western public opinion regarding things such as Ukraine? I find the latter much more likely.
Well, first of all, Russians who actually speak English can get a much better job than that. Second, the government propaganda in the Western mass media has shaped the public opinion regarding Russia for over a century now. It would be a waste of time. Third, Putin stopped caring about what West thinks about Russia two years ago. Previously you could see that he sort of tried to build a working relationship with EU and USA, but it was very much an one-sided effort. So he stopped caring and annexed Crimea. And fourth, you underestimate the number of internet savvy Russians, I think because this part of the internet exists outside of what most people usually see - same for Chinese internet.
Tu si se zajebo. Sasvim solidno "citam" srpski i ostale bivse Yugo jezike, osim makedonskog.
There is no need for this kind of vulgar speech. It is good for you that you can read Serbian. Also in cyrillic or is this the reason why you have a problem with Macedonian? Because for me it is not more difficult than understanding Serbian (I speak Russian pretty well and also have learned Czech).
Anyway, then you might have seen a Putin paid shill indeed.
