Anyone with karma > 30 can flag a post or vouch for a dead post. We try to review all the flagged submissions but there are too many for us to look closely at them all.
No, that seems a fair request, I like that idea! But I can also see that it's not likely to be implemented.
Though I'd see that transparency as a step forward, it's very likely to generate flamewars and even more discussion on the topic. If I was a mod I'd probably weigh the pros and cons of that to be negative overall.
