Posts with more comments than upvotes trigger the HN flamewar detector, and are penalized. This thread is at 300 comments for 200 upvotes. There's no downvotes for submissions. There's flags, but it'd be quite hard to coordinate a submission to be flagged just enough to get it off the front page but not enough to actually mark it as flagged.
