After a certain amount of downvotes a post gets flagged and can no longer be seen. A post must be flagged separately from downvoting to become dead. It might look like heavily downvoted posts get killed automatically, but those are just correlated events. A post that attracts a lot of downvoting is also more likely to attract flagging. A post that is already in the most-downvoted-possible state (-5, I think) can get more downvotes but those just won't do anything at that point. I have not flagged or downvoted your posts. I just want to clarify this point of HN comment logic.
