I received this email yesterday, it did make me chuckle. I was kicked out of the program six years ago for something that I didn't do. I had no way of proving myself innocent so I was therefore announced as guilty and kicked out. Middle of last year they pretty much invited me back. Google brought their collection of products together so I only have to log in and see them all listed. Adsense was never there but one day it was so I clicked on it and reapplied. I sent them an email telling them that I was reapplying. They accepted me. Fast forward to a year and I suddenly get that email. I know there are a fair few people in here who have been banned from Adsense and were let back in, I'd say beware that they might kick you out very soon.
What exactly did you or what policy did you break to be banned? I think I better create a new thread for this.
I was also kicked off last month from Adsense. Same stuff with no reason. Always look for backup. I am trying two adsense account now
Maybe you are using blackhat methods to earn money from adsense? This is a common reason why people are getting disabled.
I think people who use black hat methods are also making life difficult for ordinary white hat publishers like us. If I were you I would call google send them emails and do everything possible to explain that I ain't done nothing wrong. Sad story bro.
