If a domain name banned by adsense or google is already deleted on the registry? Will the ban also removed? What if i accidentally registered a previously banned domain name? Would this mean that i wont be able to use adsense on that domain name?
I believe you can email adsense & ask them to lift the ban. Explain that you are the new owner of that name.
Iwebtool has a Banned Website checker http://www.iwebtool.com/google_banned . Maybe you could take a look at it.
