Do you really need to post personally identifiable information in a public place? In the Netherlands it's not even legal, not sure about where you live. And regardless of whether it's legal, it's not done. I wouldn't want my information to be posted like that.
Oh and if you say "he asked for it", well yes but you got the wrong person, so that's kinda screwed up for whoever happened to own that domain.
That's the output of whois voidnull.com. Too obvious to be the guy making the challenge, of course, but it's not exactly classified information, and has already been "posted" in a public place (the whois records).
