If it went from being on the 1st page straight to the 3rd page (say from #15 to #75 or so), I believe that is an admin kill that any YC founder can do. They don't seem to have particular standards for doing them. If it dropped significantly less than that (say from #15 to #35 or such) that would probably be the net effect of a number of normal users flagging the post. This Ask HN post will probably end up being admin killed (or whatever the right term is) as well, they don't seem to particularly enjoy discussion of what's behind the curtain.
