This is the mail I got from Google Adsense.
Hello Sharique Ahmad,
Your AdSense account was found to be related to an account previously disabled for invalid click activity and we have therefore disabled your account. Publishers disabled for invalid click activity are not allowed further participation in AdSense and do not receive any further payment. The earnings on your account will be properly returned to the affected advertisers. As outlined in our program Terms and Conditions, Google reserves the right to terminate any publisher’s participation at any time.
