Looking at your comments- it seems like for all of your karma, you generate a lot of content on HN that is strictly policing: https://news.ycombinator.com/threads?id=dang

Just imagine if you will if all members of the site created similar comments constantly. That would hide all of the discussion relevant to the topics being discussed.

But, I agree with what you said- I don't like it when people enjoy suffering either. I just think that possibly the best way to handle it would be to just ignore those posts, as you might elicit more response from them.
