My HN account email is sleepy.home9993@[mydomain]. My email provider (FastMail) creates these "masked emails" at the click of a button, with a Description field so I can identify the purpose. Each email address consists of two random words plus a 4 digit number. Then I just store the information in my password manager.

I'm not wasting time trying to fix the breaches. I can just nuke that email forever.
