If you have realistic and normal leftist takes you don't end up going "farther left" to soviet bootlicking. I think tankies are just too closed minded / dumb / lazy / impatient to see the incremental path towards socialism that other leftists seem to focus on.
Oh, well look up Caleb Maupin. He was a big tankie figure online and even offline, and he had literally worked for RT News in the US and presumably had been in contact with / paid by Russia.
It's not really "right wing" astroturfing, as you seem to mean it. there are well publicized social media influence operations run by rogue states, with the apparent goal of steering and polarizing political discourse the US and Europe. and you are falling for it.
I took your comment to mean you believe it is actual right-wing (e.g. Republicans, etc) astroturfing, as opposed to state-sponsored trolls. But perhaps you think of those governments as right wing and that's what you meant.
Shit, it doesn't even have to be incremental. "We need to overthrow all bourgeois states NOW" may be a ridiculous take, but it, at least, is a product of idealism, unlike, say, the position of "It was actually really vital that the Soviet Union killed all those kulaks for having 100$ worth of property" that tankies have.
