hey if u are once banned from adsense program is there no way to get back into the program and get back the earnings with a excuse???
The only way back is to ask them and to explain why you think you got banned and what you are going to do to prevent it in the future. If you got banned for click fraud you won't get back in and you wont get the money, And rightly so.
Yes, you can try to make some excuses, but it won't give any effect now - but after couple of months it could succeed.
