The problem with this is that it assumes that the only (or main) source of disinformation, propaganda and manipulation is the government. These techniques are used on a daily basis by people on all sides of every issue. Is it possible that some of them are paid government "spies"? Sure. However, it's likely that the vast majority of them are just independent trolls, skillful manipulators or bad arguers who've discovered that the techniques in question are an easy way to manipulate the discussion so that they can get the validation that they crave.

I think that the document itself merits some analysis when it comes to manipulation and disinformation. If you take the document at face value, the author's intention is to give information to other activists so that they can protect their communities from government manipulation. However, I think it's also possible that the list of behaviors is meant to be used by leaders to purge communities for (internal) political or personal reasons. Given a long enough posting history, you could use this list to accuse almost anyone of being a spy. I suspect that whatever the author's original intentions, the latter interpretation is going to end up being much more common. It's already easy enough to dismiss people who disagree with you as "government shills", and this will simply make it even easier to justify.
