about one and half year ago my adsense account banned due to fraudulent clicks (i did click fraud) but after one year i still can't access my account and i couldn't reactivate my account
Who told you they will give you account back after one year. Once you get banned for click fraud you are banned for good.
Try to make a new account or try to get the old one reactivated. Just stop clicking your own ads and you should be ok.
First if you are banned. This is for life. Try another new account, new domain, new address and new name you can do it easly.
Google never gives the account back. I create a new one after my account ban. How to get a faster Adsense account: 1. You need to create a new Gmail account 2. You need to create a Blogspot blog account with that email account 3. Apply for the adsense account with the url of blogspot blog I have done so many time for my student and they get there new account in 2 to 3 days The quickest adsense account i get in 3 min.
