Very late reply, but for context. I had done the upvoting of downvoted comments just a few dozen times total. > If a user however upvotes more negative comments than positive ones that is at least unusual. I disagree. There is no real point in upvotes IMO. Nothing visibly changes, and comment "karma" is useless (on all sites) and mostly encourages unhealthy obsessive behavior of karma chasing. Downvotes on the other hand are clearly visible and change reading and voting pattern and flow here on HN. To me, using voting privilege on wrongly downvoted comments makes a lot of sense to me. > all downvoted comments are often downvoted for a reason I took great care to only upvote clearly innocent and worthwhile submissions and not the haters and the useless (even if innocent) stuff. I tried acting responsibly and only after giving the value of the comment some thought.
