I agree some HN users are overconfident, and education and even demonstration can be valuable. But, your experiment is quite literally a crime in many jurisdictions: obtaining identity information using false pretenses. You could be fined or jailed for such an educational 'prank'.
If i were to save the info in a useable form, then yes, but identifying information (names and email) was only saved as a hash, not as plaintext.
That of course makes it impossible to see if people enter fake information or not but I'd hate to give a bad guy the opportunity to hack the server and walk out with the info.
