That's probably how the poster knew it was wrong.

I never have more than one account at a time. I can get addicted to social media, like everybody else, and sometimes I find that I'm wasting way too much time talking on HN (and sometimes having arguments). I also dislike a permanent backlog of everything that I've ever said being attached to me. When I feel this way, and when I feel like noprocrast isn't doing a good enough job modulating my addictive tendencies, I retire my account (locking myself out of it intentionally) and take a few months away, usually eventually making another account.

You're being needlessly aggressive and making some uncalled-for assumptions.

Weird ad hominem flex. And "across" doesn't imply multiple accounts at once. People who register with their company email may be forced to create a new account when they leave the company (perhaps with sudden and unexpected loss of access to the account).

Here's the actual guideline (not rule):

"Throwaway accounts are ok for sensitive information, but please don't create accounts routinely. HN is a community—users should have an identity that others can relate to."

People have commented both appreciating your clear definitions and calling you out for the condescension, with a perfect xkcd suggesting an attitude change. It's up to you how you react to such feedback.
