Many of the rules of HN aren't published in a straightforward list; you learn them by following the log of moderator comments. That, too, has been has been explained innumerable times on HN: it's a common law system, not a civil law one, because if you build a site for nerds around a rigid set of enumerated statutes, the nerds will spend most of their time looking for clever loopholes (I'm not disparaging them; I'm one of them).
From the way you've written on this thread, it seems pretty clear that you're not the kind of message board nerd that makes 'dang's comments a daily read. That's fine! You have to be a pretty extreme nerd to do that, and there other, probably better things to spend those nerd points on. But you should take 'pvg's word for it on this stuff. He's not messing with you: he's trying to explain to you how the site works.
