Unfortunately people are often entertained by truly horrible responses to things, and so often the worst comment would get the most likes or votes or whatever, which means it rises to the top... which then encourages people who like attention to try harder to be more awful. It always makes me sad when you see kids respond with "kys" (kill yourself) because they didn't like something or didn't agree with something that they didn't have to click on.

I love that Steem doesn't really have that side... you see a few douchey acts here and there, but on the whole people are genuinely supportive and kind.
