I you happened to know how to block adsense showing to visitor from certain countries, please let me know. Or there is another solution to avoid smart pricing policies or click fraud
You can block countries from your website by IP address but I'm not sure if you can block ads alone. Anyone?
On blogspot it's difficult. You can do it with htaccess and PHP, but on blogspot you can only use javascript. Find the list of IPs at http://www.blockacountry.com You could add those IPs in a big javascript array and then decide to redirect to another site if the visitor uses an IP from one of the countries listed. But the Array is going to be huge, not very good for other people.
Please tell me how to built that JavaScript array, i'll add the country code myself. this is a serious problem for me. this click fraud has to stop someway
