AFAIK you're not able to delete your stack overflow / stack exchange posts either. The site basically says anything you post is CC-BY-SA 4.0 so once you post it it's effectively available for everyone forever.
You can delete your account but your posts will not disappear. Maybe HN should add the same terms so you know your posts can't be deleted.
As for deleting your account that's annoying. My solution for at least not using an account is setting minaway to 9999999999 and the turning on noprocrast. suddenly my account is unusable.
Maybe a simple solution for HN is they could follow S.E. and when you delete your account they just change the username to user-<number>
