Slightly off topic, but the page says "we don't want your email" and I vaguely remember a site that was looking up public keys on GitHub and getting the email address from the GitHub account. Not sure if I got that right, or what the site name was, but it's definitely possible to get public keys from GitHub users like so: https://github.com/binwiederhier.keys https://github.com/binwiederhier.keys If you mine these, along with crawling GitHub for email addresses, you can map public keys to email addresses.
