Get some good traffic, like thousands of unique visitors per day and then try other networks. If you want to get into google adsense again then try these Change the IP address you use to log in all the time, Change the domain name you will be using adsense on, Change the WHO IS information of the new domain to a new mailing address. Use another email ID and another name for the account to get payment checks on. I am not sure, i just added few points to what all guys said above. BTW how did u get banned 2nd time? did you get a second chance to use it or did u try something weird like i just said?
