Website is Banned from Using AdSense?
There is no surefire way to check if a website is banned from using AdSense. However, there are a few things you can do to check if a website is banned:
-Check the AdSense Help Center to see if there is any mention of the website in question.
-Try to create a new AdSense account using the website in question. If you are unable to do so, it is likely that the website is banned.
-Contact AdSense directly and inquire about the website in question.

Tips:
Although a Google AdSense account is not domain-specific, it is linked to a Gmail or email address. You cannot use a mail ID that has been deleted earlier. Use the Principle Domain, which has never been used, and register for AdSense with a fresh Gmail ID. Delinking your domain from an unapproved Gmail ID and then re-linking it to your dedicated, fresh Gmail ID is preferable. Make sure your domain has enough content and complies with all Google AdSense terms of service before submitting.
