I think that it's arguable that the Khmer Rouge carried out the closest attempt at pure Communism, but it's not like that turned out all that well. That said, plenty of people associated things like the Stazi/KGB with Communism. I haven't actually read Marx's manifesto, but I highly doubt that his "worker's paradise" involved disappearing masses of people and a "report your neighbour, Comrade" mentality[1].
