When Uzair signed up on ClixSense, he was in India.
Anyways, I'll explain this a little more. ClixSense sometimes blocks registrations from certain countries if the amount of fraud from those regions increase. But, members who already signed up from those countries are not banned/suspended unless they cheated.
Saudi Arabia was opened for registration in March last year. I am not sure when they closed it again.
Here is another member from Saudi Arabia (so its not just Uzair
) - VPN | ClixSense Forum
