I was going to mention that earlier, not sure what google's stance is on just .cc. As far as I was aware co.cc is not a real gTLD, it is merely a domain name of "co" registered under the .cc gTLD and they allow people to freely register sub-domains of the co.cc domain.
So in google's eyes they are not blocking a gTLD but blocking a single website and all it's associated sub-domains.
