Why are you even discussing tort law? Feelings are not damage. Has your emotional psyche has been permanently affected leading to challenges in how you function and cope in life? Feeling sad or frustrated or annoyed because your question was downvoted is not emotional distress. And what does this have to do with Stackoverflow? What's the duty of a commenter? How do you know the intent? Who's getting traumatized by that site specifically?

You're reaching here and if you are more affected than average by comments from other people (on SO or life in general) then perhaps you should work on that instead of claiming emotional suffering.
