My friend got this mail from google few days back. Hello, We continually review all publishers according to our program policies ( http://www.google.com/adsense/policies ) and Terms and Conditions ( http://www.google.com/adsense/terms ). During a recent review of your account, our specialists found that tamper data was used to modify the country listed in your account. Changing your address in this manner is a violation of our policy guidelines. As a result, your account has been disabled. Please keep in mind that Google reserves the right to disable AdSense accounts or ad serving to sites that do not comply with our program policies. Additionally, as stated in our Terms and Conditions, publishers who have breached this agreement may not receive further payment. The earnings on your account will be properly returned to the affected advertisers. Please note that this step was taken in an effort to protect the interests of our AdWords advertisers, and to maintain the quality of the AdSense program. Thank you for your understanding. Sincerely, The Google AdSense Team
Asking the same question. Searched Google but no relevant results. EDIT: So this is how it is. For those who don't know yet: http://www.artima.com/forums/flat.jsp?forum=126&thread=274780
well in some countries they are not allowed to create an account until their blogs reach 6 months. in such cases they register via another country and change the country by tamper data(it is a firefox add on)
