The problem is that it's no longer individual bad votes. I would estimate that at least 1 in 5 of my comments are voted down (albeit just to zero) with no obvious reason why. While the rest of my comments are typically voted up fairly substantially. I don't vary the quality of my posts and try not to make a habit of commenting on topics I'm ill informed in. So either I'm being singled out by an individual with a grudge (which I doubt but I think HN is smart enough to detect those kind of voting patterns anyway?) or the moderation system on here is broken. Either way I can't predict which posts will get voted on in which way and the individual bad votes have now become anything but sparse.
