Please keep in mind that you're not entitled to badger here; this isn't a venue for convincing people that you're right about things (for what it's worth: I'm well aware that you are right in this instance), but rather for having thoughtful conversations.
Wikipedia has a good rule in Articles for Deletion debates, where they decide which articles to keep when people nominate them for deletion. They're not votes. You can get all your friends to chime in with dumb comments saying "keep" or "delete" for stupid reasons, but the admin who evaluates the AfD debate is supposed to ignore the count of comments supporting any given argument, and just make a note of the diversity of those arguments, and then evaluate which set of arguments are stronger. You can spam an AfD with misinformation, but at least in theory it shouldn't work (in fact, you might be just as likely to piss off the admin and nudge them the other way).
That's a good way to look at HN threads as well. If you have something interesting to say, say it, and then get out of the way; let the dumb comments be the noise, not yours.
This is all very meta, I know, but this whole thread is so pointless that meta can only improve it.
