Hi, I have find good tool to check site if its banned from Google or Not, I am here with this link to share with all of you http://www.vebtools.com/google-banned-checker/
I am not sure about the accuracy of the tool, checked a few domains and got a response for pubwebhost.com to be banned, whereas the site has PR2 Cheers
Thanks for sharing it. Its a nice tool. You website must have PR2 but its no more same. Your site is completely deindexed. -DS
the best way to find out if your site is banned by Google is to use "site:www.yourdomain.com" if your site does not come up. Then is either banned or not indexed, either way its a bad thing.
