Hmm. Interesting. If it was [dead], probably a false positive from a naughty comment filter; if it was [flagged][dead], difficult to say, potentially even an accident, or maybe people didn't like the joke. Given the non-negative karma, I would guess the first. Regardless, I appreciate the vouch.

It was just [dead] before I vouched for it. Luckily we have vouching–HN is my favorite moderation system I've seen.
