Ran into an interesting situation earlier today with points and comments:

It seems that a certain post was rapidly upvoted then downvoted -- which then resulted in it being ranked higher than some positive comments (ignore that pun).
Looking around, I couldn't find the link for reporting bugs, and I assumed I shouldn't send this to the ycombinator info email address.
Thoughts anyone?
