I cannot understand the point of hiding deadened questions while still keeping the comments? It makes sense to me. If the users flag & kill a link submitted by spammers, the spammers get no value from it because, by default, a spider won't be able to follow the HN page to the URL the spammers wanted to promote. But keeping the comments helps users at HN get a feel for how the article was initially received.
