I couple of months ago I sold a website, I deleted all the adsense ads from the domain but somehow the site was restored by the hosting company and now that site is displaying my ads. I do not have access to the website and the site owner will not reply my emails. Please help!
Contact AdSense before you get a possible ban. You may also contact the hosting company and explain the situation. How do you know?? Give it a try as well.
Contact AdSense to alert them to possible click fraud. Other than that, if it's your ID and there's no click fraud, what are you worrying about? If the ads generate any income, the income goes to you.
