Ask HN: Why aren't users told when their HN accounts turn 'dead'

If you change your settings to 'show dead' you will find lots of comments from users who are totally unaware that their accounts are now 'dead'.

Dead accounts can still comment, but their comments can not be seen by most users, and cannot be upvoted. Since I started checking a few weeks ago, I've found about 100 people who were happily posting away, wondering why they never received any comments to their comment, or new karma, but happily taking part. Once told these users can usually search back through their comments to one heavily down-voted post that killed their who account.

I understand that users don't register with emails, but surely there could be some way of letting people know their account has been closed (and why), so that they know to modify their behavior.

Many of the dead comments are fine and on topic, and are written by people that want to be (and think they are still part of) the great community HN has here.
