You should mount an appeal offering to provide any help you can. My account had been reinstated before on appeal. However, there are others who have been told that although they are probably innocent, Google will still not re-instate their account because of the risk to their advertisers. The bottom line here is that somebody can get your account banned on purpose. Therefore, it is best not to rely too much on Adsense as your main means of income.
Just out of curiosity what reason was your account disabled for ? And what evidence did you provided ? My appeal resulted in them saying that the clicks where valid but my account is "dangerous" for AdWords users . I intend to file a second appeal since i still have one site that sits around whit traffic and no profit .
If it was a site ban, there were chances of getting that site restored but in the case of banned account I don't think there is any hope.
Why feel so down about being banned by Google? If your site is good enough, go for other PPC adnetworks, Chitika, Infolinks Etc. Try Cpm advertising and pop unders,,to make up for the lost adsense revenues.. try CPA networks...Google is not the end of the world...Good Luck..
