I Have a Suggestion for Similar Worlds

I would like to see a 'dislike' button. I could have used one several times on people who make unkind, unsupported and derogatory remarks on others stories, questions, and even to those who have commented on someone else's posts. They shouldn't get away with no one having the opportunity to show them that something was inappropriate without having to post and get into an argument with the instigator, which I've seen a lot of.
