I am always in favor in open information on general principles. Outside of that, I don't care.
Leave it. If you make people accountable for their negative reps, then people won't leave them.
I'm not sure that's the case. People attack others all the time it seems in normal threads with names attached. I'm sure there would be some loss of negative reppin' if we did this though but is that a bad thing? There are a ton-o-negative reps that are personal attacks which I don't think is fair. It should be based on the content and contribution.
