I find the "I disagree with you so I'll downvote you" approach to comments is quite useless. Should require a comment in the very least if you have any concept of adding value. Especially in political discussions I've seen. Its blatantly obvious someone is downvoting simply because they disagree. That should be trackable and that type of action flaggable in itself. But I understand the overhead it would create. Flagging without reason is likely equally obnoxious. If the downvoted person nas to wonder about the reason "why?" then the system isn’t helping. I've seen plenty of faded out, non-snarky, non-trolling comments that were actually on-topic and relevant. But enough people didn't agree. Making them hard to read just means I now apply a extension to find out why it is being blocked. Often the faded out comment is informative specifically because it annoyed or offended someone who disagreed. Looking back at some of my own comments that were downvoted, I have no idea why it happened. I asked others for their opinion. They have no idea either. So what was their intent? I literally don't know why. No self reflection occurs because there's no clear reason.
