As I browsed the BST section of the community, I found a great website that is used to check whether a url is banned from adsense network or not.
I found it pretty useful as it allows to check if the URL is not banned from adsense. Very helpful site for website buyers IMHO...
Here's the URL - Banned by Google or AdSenese? - Free Banned Check!
P.S - Mods, This is not a self promotional post. I am in anyway not connected to the url above.
