If you're really concerned, email dang (hn@ycombinator.com) and ask him to look into it. As a sidenote, if you actually flag out of suspicion of a voting ring or other feelings without real evidence, it is abusing the power you've been entrusted with. Threads like this one are also way off topic, seems more considerate to submit an "Ask HN" post rather than hijack the story discussion.
The group dynamics are often surprising on HN.
