I think in Europe the domain name providers (or would one rather call them resellers ?) switched to redacting all private domain holder information since a few years. It was actually quite horrible like it was before, so much email spam, a free ticket for spammers to put all those Whois information wide open on the Internet.
Some providers, like Greenhost in NL, provided Whois masking (cloaking ?) for customers paying a bit more.
