dang, I assume you meant stop bickering, but if you absolutely mean no more posts, sorry for this. It will probably be the last anyway.
I'm just curious, since you (ferrari) and anyone else still reading this have more knowledge or experience about this, has any site, or even HN, ever tried making the usernames people who upvote and downvote publicly visible?
I think people would put more thought into what they up or (especially) downvote if they could not 'hide', and their usernames were attached to it. Likewise, if voting had a 'cost', say, 1 karma to upvote and 1 or 2 karma to downvote.
A top poster with privilege, tptacek, claimed on a detached (by dang) thread that seeing who downmods me is "really none of [my] business"[0]. I would guess the same applies to you.
