Tell HN: I'm getting spam on an email address only ever used to sign up to HN
Basically thread title. This email address has only ever been used to sign up for HN. I have never posted the email address and never set it to public. What gives? I'll paste a copy of the relevant email headers and the text of the email below. The email is designed like a Docusign lookalike, including Docusign logos.
