He actually bought his domain via a website that assures total anonymity for their clients (domainsbyproxy.com in this case) unless someone files a complaint (which you can do if you go on their website).
His servers are hosted by GoDaddy, which is a fairly known web hoster, although if you want to do something about it Domains By Proxy is the way to go to file a complaint.
This info is really easy to get btw, I’m not sure if I’m allowed to post more info than what I already posted (like the owner’s domainsbyproxy email address, among other things) but you can easily find it if you use the GoDaddy WHOIS feature on their website and just type *** in the search bar.
