>Disapproval without explanation is not the converse of approval without explanation. So maybe have "ignores" on your user page, or perhaps some other thing like that a way to "downvote"? I do like the concept of a downvote, the idea that the community can decide what things are definitely bad and should be hidden away. However, I think it needs to be a system that is less a downvote and more a report system. Perhaps add a "requirement" to downvote that displays your name in a comment where you explain what you did. Leave the comment blank and you will similarly be disliked because you just attacked a person with zero explanation. So a comment highlighted in blue is one which represents that the user also committed to a "I want this to be hidden" report. That way you know what is wrong and can go to improve. And have a way where if you up... node? dot? hub? attach? a comment that is a downvote, it adds your name to that comment and adds another downvote to the comment above it.
