Will mention though that I’ve had wholly uncontroversial HN accounts, with positive karma, deleted after suggesting teddit.net, only stating a link to the about page, in a thread.

I am mostly unbothered by it since the bar of entry for creating an account on HN is so low, and you can read it without one, but am still confused.

Perhaps there is auto moderation that deletes an account if it posts a comment with only a link?
