Google AdSense Illegal Behavior Collection

In order to ensure the quality and reputation of Google AdSense, we will review all the publishers who apply to join this program in accordance with these plan policies. We also monitor the websites that participate in the program when they start to display Google ads. Whenever we find a website that violates our policy, we will warn the publisher or suspend or even terminate the account.
You may notice that certain policies relate only to publishers who choose to accept specific Google services. For example, references to the search box apply only to publishers who choose to accept the Google Search service, and the policy for placing Google ads on the site is only relevant to publishers who choose to accept content ads. Please read these policies carefully, unless there are other clearly stated policies, it should be considered that all these policies apply to you.
Please note that we may change our policy at any time, and in accordance with our terms, it is your responsibility to always comply with the latest policy provisions we have issued here.
Transfer of an account
When you sell a website or make other transactions, the AdSense account is not transferable, transfer or resale. For example, when ownership or management of a Web site changes, the previous owner or manager must revoke the site's AdSense account, and the new owner or manager can register the new AdSense account in his or her own name.

Alternative advertising
If you choose to accept content ads, you can always make sure that your ad space is used efficiently by specifying the selected image or Ad Server-either for targeted Google ads or for the content you choose to put on your own. However, you cannot designate Google ads as alternative ads.
