Don't loose your Adsense Account.

Google Adsense of yours may get in to trouble once they make the Privacy Policy is a must on your web pages. You joined their program and waited for to be approved. And with much care you are doing every thing to gain a steady income by showing advertisement in your web sites. Recently they
announced that your web pages which are showing their Adsense Program services must have a Privacy Policy. If it is not there you may loose your
participation permission.

Now all your web pages have that policy which has been placed by you. If a person ( a person who know and hate you or a former employee of yours)
place your advertisement codes with your publisher's identification in a web site where there is no privacy policy, what will happen?
You are running your advertisement Champaign in an unauthorized manner, is it correct?

If they found out this, you will be in trouble. So how you can prevent this?

For this kind of things, they already gave you an option in your account. There you can define the names of the web sites and sub domains which
are participating in the program. By giving the names of the web sites and sub domains for your publisher account you are safe when someone use your codes knowingly or unknowingly on another web site, which they will ignore and will not take the income in to your account also.
This is an important step you have to take to avoid unnecessary situations while participating in their program.
