I have not changed my stance on anything.

Do not make deletions out to be more work than they really are, as others have mentioned the suppression of content from a particular account is already implemented to combat spam. Anyway, deletion of particular message is technically the same as allowing edits after 1hr with a fixed replacement text (such as "[deleted by user]").

User-triggered account "deletion" would be a trivial addition instantly obviating recurring, tedious discussions like this. Even Google lets you retract your submissions from their usenet archives and Groups in a simple way.

There are many valid reasons why a user may wish to have their messages removed that override the interest of forum integrity.

No right lapses after one hour since there is no permanent license grant for user submitted content to HN in the first place (lack of TOS). The copyright of entries remains with the user.

Spam is not eliminated by deletion, it's eliminated by killing. If you set showdead=1 in your preferences, you can see the spam. It's annoying.
