You can get metadata in order to preserve the comment tree, but it won't show the text for quality control reasons.

You can see dead/flagged comments via a setting, perhaps only exposed to users if their own score is high enough(?).

I've thought about making a site that publicly indexes and exposes all flagged and dead HN comments and stories.

Occasionally there are gems.

You should be able to turn on the "showdead" option in your user settings to see the text. But (like the other user) I'm not sure if there's a minimum karma amount for that toggle to show up.

I was referring to the API.
