I also did not use the Allowed Site feature before, not knowing if it's useful or not.

But after my entire site was copied -- Adsense code and all -- I realized the huge risk and started to make use of that feature.

It's hard to prevent someone from copying your site and Adsense code, so at the very least, tell G which sites are yours and where your codes should only be found.

how do you tell what sites are using your adsense code?

1 - search for your Adsense code
2 - look at your analytics to see if any site is suddenly bringing you an abnormally high traffic
3 - routinely search for some sentences in your site

In one instance, a visitor emailed us to let us know that he came across another site that has the exact site design and content of our site.
