That works for site maintenance and garbage collection but it doesn't stop them appearing in search results which is where my problem lies If I see a StackOverflow result in my search I'd wager there's a more than 50% chance it's a closed question without an answer. Sometimes I'll grant if it was marked dupe I may end up finding the answer, but honestly the only visits I really remember are those that are marked dupe and link to something sounding similar but completely unrelated
