You mentioned "results of elections all across the world". I see Benjamin Netanyahu, a facist who lost election after election now trying to take absolute control over his country. I see fascists in America trying to steal elections with 40% of the vote when the majority of the population doesn't want them. I see Lukashenko imprisoning his political rivals that appear to be supported by a majority of people. Conservatives don't believe in democracy. They don't care what people want. They just want the appearance of legitimacy that democracy provides. Creating fake supporters online is just one tool in the aresenal to create the impression of support where none actually exists, to make their fascism easier to pull off. You can think of astroturfing as reverse censorship, and it's just as bad.
