One important way to prevent your Adsense account being abused, is to use the Site Authorization.
What Is Site Authorization
It is an optional precaution feature for Adsense publishers.
With Site Authorization, you can identify your verified websites or blogs as the only sites that are permitted to use your Google ad code.
It is a good way to prevent malicious use of your Adsense ad code by other people.
They copy your ad code and paste it on their sites which could violate Adsense policies.
When that happens, you will receive a policy warning.
If you do not take action, you could even lose your Adsense account for good.
How Does Site Authorization Help
If you have the Site Authorization feature enabled, should a URL displaying your ad code is NOT on your list of verified sites ads, the ads will STILL show in your URL and impressions and clicks will be recorded.
However, advertisers of those ads will NOT be charged.
In other words, you WON'T be earning any money for the unauthorized site.
In addition, you won't receive any warning, and you won't be penalized for any policy violations.
Note: If you don't add a site to your list of verified sites, and you place your ad code on it, ads will still continue to appear on the site.
But you won't earn a single cent from Adsense.
Therefore, enable this useful feature called Site Authorization and keep enjoying the valid income from Adsense.
How To Authorize Your Websites Or Blogs
Here is a simple step-by-step procedure how to enable or setup your Site Authorization:

4. Then another drop-down menu. Click on "My sites".
6. Click on the three dots on the right side of the page.

That's all you need to setup Site Authorization, to authorize your verified sites to display Google Adsense ads.

You need to confirm your ownership of these sites by verifying them.
Here is how you do it:
