Google removed .co.cc extension domain name sites from it’s index
About an year ago, extension .co.cc was being allowed to be registered for free (yes, free!) by a Korean company as they control this extension. Now this extension is being removed by google in its indexes as lot of spammy sites have got this. So you won’t find any .co.cc extension URL in google search as it won’t index it and all existing in its indexed database have been removed. I suppose as they were being offered for free with DNS server, lot of spammy sites got registered as it was all free with no single penny to pay for.
