I think news.yc has a 5th troll behavior and it's down modding a comment because they disagree with it. I have been down modded a number of times not for saying something rude or stupid just something that others don't agree with.
I tend to down mod rude and aggressive people on here and I also up mod people who I think have been down modded unfairly.
I am not sure if I am alone with my way of thinking.
