Could you elaborate on why it's obvious why you won't name the account?
(I don’t know who the comment is talking about, which is how it should be. There’s no need to blow someone’s cover in a highly visible way. Even if they were satan, they’d still be welcome on HN as long as they’re writing substantive, interesting comments that follow the guidelines.)
I would say it's obvious why one might respect that wish (do unto others...), but I'm also aware that my and my culture's sense of privacy goes further than many others'.
