Yeah that's a getting-trolled trap, I think, and it will increase ad-hominem, which I think is a problem we do have here sometimes (not as much as elsewhere though)

My current anti-ad-hominem solution is a little plugin script that hides an item after I downzap. That way I have said my say and I no longer need to get bothered by it. It would be a good replacement for some mutes I have. My downzap helps ranking decisions - even if it is a mild downzap - but I'm also not annoyed by crap I already downzapped. Also prevents zap wars (to a point - can always wage anon/sybil-zapwar)

I think the solution should not be sought in punishing people for getting downzapped. My biggest downzaps were for hiding my badges... it's already punishment enough that I got downzapped to oblivion and I spent effort for nothing.
