I don't think dang can do anything about it, I'm sure HN gets scraped all the time. I routinely get spam from cryptocurrency startups to (obfuscated) email addresses I have posted on HN years ago on "Who Wants to be Hired" threads, and from my commit messages on github.
Github is definitely quite the source of spam. I ended up realizing that when I was tired of having two .gitconfigs with two email addresses (work/personal) and switched to just putting my @users.noreply.github.com in there. No more spam.
(Plus I get to show off my 4 digit Github userid. I was the 2367th person to sign up! ;)
Neat. I was pretty late to the party and have a userid halfway into the 6 digits, but somehow I got extremely lucky and landed a two-character username (my initials).
