I have after some thought and chatting with someone have come to the conclusion it is better for the end users if I remove the co.cc domain block so now I accept co.cc proxy sites.

Also any sites submitted are automatically added to my Twitter page. If you don't want your proxy to be added to Twitter let me know and I will remove your link from Twitter account. This isnt a new feature but not one I mention in public.

Thank you
Mr.Bill
