I can't comment of DF specifically, but as someone who uses the "flag" link when I think it's appropriate, I see people complaining all the time that their pet topic was flagged/downvoted, and then they instantly go to "the mods"/conspiracy mode, and I'm thinking "I'm just an average HN user, and I just thought the topic sucked or was inappropriate for HN. No 'conspiracy' needed, we just don't like your content."

All I can say is that I found this particular DF post annoying and narcissistic to the extreme. I'm glad it was flagged.
