These trolls really exist on Russian social networks, trying to refute any news from the opposition media. And some people (Russian enthusiasts) count and list these bots. But your article does not prove it to me, because some Russians are afraid of vaccinations and there are crazy paranoids in Russian social networks that convince not to get vaccinated, including vaccines that are done by Russian medicine - what do you think this proves? That Russian bots are trying to weaken their own nation? For me, these are not bots, but religious fanatics, religions often reject medicine. You may have noticed that many religions have denied the existence of COVID this year.
It is very sad that the authors of the article either believed in all these accusations against the Russians or are afraid to say that this is nonsense so that they are not accused of supporting the Russians.
I want to note that the Russian government also accuses its political opponents of being foreign agents, using the same rhetoric.
