I had one of my adsense accounts disabled a few months back. Luckily I had other accounts in GF's name etc. I tried to appeal on the banned account an got denied. Out of curiosity I decided to reapply using my old info. So I signed up using my real name, same address as on the old account and even the same website. The only thing different was that I used a new email address. My account was approved in under an hour. So those of you who have been banned may want to give it a shot just re-applying. Worked for me.
