This has given me an obscure two-word domain name, which I searched in GoDaddy - all subdomains GoDaddy sells weren't registered.
I've repeated this to give a total of twelve domains. The final two of these domains are saucepansgrooming.com and rivaledpopping.com. The other ten domains are written on a folded over piece of paper, and aside from me, the only place they have been disclosed is in a GoDaddy search (which was sent unencrypted over the Internet - so technically someone could have sniffed it). I haven't even attempted a domain name resolution on any of the 12 names.
I plan to come back in a few hours and repeat the search to see whether the names are still available.
