Strange that that single comment is dead. Usually if a user is hellbanned, this submission wouldn't show up either.

Tip: if you go to your HN prefs and enable "showdead" you can see comments from hellbanned users.

That is strange indeed. I think what might have flagged the previous comment was: I initially posted the comment in reply to the wrong person. So I deleted it and reposted it in response to the correct person.

Oh! well if you post the same comment twice, the second is automatically deaded. You have to delete the first one before you can repost it somewhere else.

Ah ha, so that must be the issue. I am relieved, now that I know the reason for the problem. Thanks, sp332.
