I have already discussed about co.cc site giving free subdomains of their site which are bad for adsense approval.Now google has removed the site co.cc as well as the subdomains from their search results .
Note: Now co.cc domain is showing up in Google search results normally as before.
UPDATE 2014 : If you want to have a free domain . Its better to start blogging with a subdomain on wordpress.com or blogger.com as they are authority sites and your blog will perform better in search results even with a subdomain on those platforms. So do go for free co.cc domain names as they might get banned again if they are used for spamming widely by other users.

Reasons for removing or deindexing the urls of the site:
1. Giving free subdomains like real domain names.
2.Co.cc sub domain sites made a mess with google search results with copied content and spamming the net
3.Many autoblog sites runs with free co.cc domains.
4.In the last few years, these domains are widely used by many users for spamming.
Due to these reasons google has also blocked their site co.cc as well form search results
It’s very bad for free co.cc bloggers.
Steps to take after google banning co.cc users :
# Quickly remove the co.cc subdomain from your blog address and change to blogspot domain name
# Submit your blogspot url and sitemap to google using google webmasters tools

Tips:
Consider posting some new content to get indexed quickly.
You can also move to custom domain names (10$)using blogger too.
Here is a 10% discount in domain name here : gowtham.bigrock.in

If you are a co.cc user do share your experiance and what steps you have taken to index your blog ?
Do you still trust any other free domain providers ? If you are using one do let us know what you think about using a free domain.
I changed my co[dot]cc domain to a .net domain after Google ban all the co[dot]cc domains. I think it is a good decision, what do you guys think??? Give me your opinion. Now my blog changed its name as http://www.techblaster.net
