I don't really read this terribly as complaining. It is an interesting analysis of some posts (including his own) that seemed to behave atypically in a non-transparent manner to the user base, that may suggest some manipulation of the ranking. At no point does it seem to take any accusatory tone, or complain. The hypothesis may be incorrect, but it is not unreasonable, and it does seem relevant to readers of hacker news. I don't think being "bored" by something is generally considered a good reason to flag content. I don't see how it could possibly be considered off-topic either.
