Google blocked all CO.CC subdomains from the search results

In order to fight against web spam Google, the giant blocked all co.cc subdomains sites from its search results. Co.cc is a domain used a company that offers subdomains in bulk, to anyone interested in this sort of deal. Many people start registering CO.CC domains since its given as FREE. They start a website with CO.CC copy & paste some contents and make the website as junk to get a Google page rank. This started attracting so many spammers.
It seems that Google has had enough from co.cc-provided websites and has now blocked the entire domain. Checkout the below screenshot.

Matt Cutts Remarks:

“First, a definition: a ‘freehost’ is a domain that will let anyone register a site on that domain. There’s lots and lots of high-quality freehosts out there (wordpress.com comes to mind),” Matt Cutts wrote, onGoogle+. Matt Cutts is the head of internet spam in Google
“We absolutely do try to be granular, but I wanted to mention that if we see a very large fraction of sites on a specific freehost be spammy or low-quality, we do reserve the right to take action on the freehost as a whole,” he explained.
“I think most savvy search/SEO folks would understand this completely, but I figure it’s better to over-communicate than under-communicate,” Matt Cutts added.
Though some bloggers are having good sites with CO.CC due to many Spammers I personally feel banning CO.CC in Google Search Engine is a right move to stop encouraging Spammers.  What you think?
