As a counterargument, if one is able to get past their own internal paranoia about why other people are doing the things listed here, the information laid out is quite good for what makes a bad poster bad, how to avoid them, and how to not be a bad poster.
You could argue that this stuff shouldn't be framed in the conspiracy theory idea, but then it wouldn't have gotten as much attention, which could start a discussion about the most direct way to present this information, but then if you don't give it some controversy how is it going to get the necessary exposure for people to read and listen? You might have a better manual, but if nobody reads it, it's useless.
On that note, who else wants to try writing a better manual than these guys? Is it even worth it? After all, the most important thing is to get people thinking on the right track, and stuff like this is at least a step in the right direction.
