There is no registrant info either .. only the registrar name shows up in the registry whois.
When I checked on godaddy they don't even have the whois information .. which probably means it was registered only a few minutes ago?
Following disclosure of this alleged practise, when thinking about new domain names for a project, I now don't check each one on any 'whois' service first. Firstly, I put each potential name in the browser to see if it 'resolves' at all,This is also potentially dangerous as the NXDOMAIN (domain not found) traffic from an ISP's nameservers would be valuable to domaintasters and similar. You would be better off trying anything like this with the root nameservers for the TLDs you are searching.

and i don't see how they can make money out of buying up all these names anyway. 99% of the people will just forget about it if they see the name has gone. (like you did, when your one went.) so if these companies buy up every name that gets checked then the vast majority of their expenditure will just disappear down the drain.
