How to prevent some other Pub-ID in my site?

Hi,

I am running a site called Mesothelioma. Today while examining the recent visotors and referrals to my site, I found an unique feature-- i.e a different URl referrers my site- http://emesotheliomainformation.cn/?From=com . The content is similar to my site, but the ads are entirely different- Please check my original URl in my server.

I am confused - what is going on in my site? Whether my site is hacked? Please explain

 

you can use allowed sites to use your publisher ID on adsense page

 

Yes, use the allowed sites option in Google Adsense. Also, you can load your adsense code from a *.js file as well.
