I've heard various ideas such as limiting it only after mods have expended their points (this will require implementing a cooldown to prevent a user from getting points again too soon). I want to hear your feedback, and I'll roll together something for the next major update of the site. Leave your comments
Well, one way to encourage sifting thru AC posts might be to only charge half a point to mod AC comments. OTOH, that could make downmodding 'cheaper'. :(
Personally I don't pay much attention to the userID, or lack of, when I mod. I was amused the other day to discover I'd given an upmod to a friend's post without realising it was his handiwork.
