Few weeks back Google reported that it has deleted around 11 million .co.cc sub domains from the search listing. The issue with these sites was regarding spamming which led this giant to consider their listing against authentic and genuine domains.
Various companies offered these .co.cc domains for free or at cheaper prices compared to other domains. Because of these reasons there were many spamy websites which were ranking higher against other genuine domains. Many companies also offered .co.cc domains and are classed as 'freehost' by Google and therefore, exercised their right to block these domains. These .co.cc domains were been registered in 1000s with Korean company offering 15000 sub domains for about $1000. That accounts roughly to about 5,741,810 different accounts, with a total of 11,403,223 domains registered to date.
The Anti-Phishing Working Group also reported some 5000 phishing attacks from .co.cc domains in last six months of 2010 alone.
