> I personally always check the posting history when I'm in doubt about the intentions of a poster. I do the same, and in the cases where it's somewhat obviously a new or 'bad intentioned' it still surprises me how fast the comments are grayed out and/or dead (often within minutes). I've always been curious how much of that was human curation and how much of it some algorithm. I've never gotten to see or play around with HN-style site data, but personally I'd probably write some code that takes into account valuable 'curator' users (with some checks and safeguards of course, and manually tagged by the moderators).
