EDIT: Thank you for your response, dang. Hacker News is a special place, which is why we have responded so strongly to today's events - I apologize if the tone above came off as less-than-civil. I (and it seems, many others) look forward to hearing more about the 'dupe' article others have linked to below. It was only upon seeing the article marked as a dupe after seeing the previous flagged out of existence that it began to feel like more than just a user-initiated action, so I am sure further information on the mod-initiated actions will put these fears to rest.
A statement would certainly be nice, however.
I say that based on looking into literally thousands of such cases, and spending god knows how many hours poring over data. My comments are based exclusively on what I know about HN—I know nothing at all about other sites because I don't have their data. But I know a lot about HN, and I can tell you that the users making breathless insinuations about this stuff have literally no idea what they're talking about. The truth is just painfully boring. (Edit: here's a detailed explanation - >>27397230 .)
As for why the comments in such threads get downvoted, that is easily explained by the fact that flamewar topics attract shitty comments, and shitty comments get shittier as people get politically and nationalistically riled.
