Well, the Soviet Union. This isn't a fully worked out position yet and I might change my mind, but my reasoning is something along these lines: Hegel regarded the State as being the perfection of rationality, since he was talking about the Prussian State this is somewhat bizarre. He saw civil society as being something separate from that. So as an analogy the forums are civil society and the forum moderators are the state. The Young Hegelians partially broke with Hegel, keeping his methodology, but with considerable justification regarded the Prussian State as being oppressive and not the pinnacle of rationality that Hegel claimed it to be. They sought to undermine it by attacking religion, seeing that as the key ideological device keeping the State going. Max Stirner pointed out that they weren't really against the State, they just wanted to have a revolution to replace one State with another. Marx's position was that the Young Hegelians placed too great an emphasis on religion and he looked to a revolution of the workers to replace the bourgoise state with a worker's one. He also regarded the division that Hegel claimed between civil society and the state as being artificial, and something that shouldn't exist.
The State in Marx's conception is an armed body of men. The state has the monopoly on violence, it is the universal oppressor, in the sense that if anyone is going to be doing any oppressing it's the State. This is fine provided it is separate from civil society, but a bit of a problem if it isn't. Using the example here, the moderators only act if the automod detects banned words such as duck (d->f) or they get a complaint, which is pretty similar to how the police act in the real world. What they don't do is engage in the debates and tell us what to say. So we can speak pretty much freely without the conversation being overtly policed, this makes debate possible. In the same way, although the State is oppressive it's a presence that can be avoided. We can get on with our lives and speak freely without worrying about whether they're listening in. Without that division between civil society and the state they're always present and any individual could be a chekist or later KGB man listening in. Basically you want the protection the State provides, but it's everyday distance makes its existence bearable.
In defence of Marx he envisaged a Worker's State and not a Capitalist one, and the Civil War and failure of the revolution to spread meant that the class that was meant to sustain the revolution and ensure it remained democratic was effectively destroyed. I don't know whether this is sufficient to leave Marx's position viable or not.
