I recently started promoting one of my sites through a PPC affiliate program with ClixGalore. I have noticed that many far east sites are sending 100s of clicks from unigue IP addresses that never go beyond the landing page. Is there a piece of software or web code trick they are using to trick the ClixGalore tracking into thinking the false clicks are from unique ip addresses?

I have banned the sites from my program but would ike to determine if there is a way to determine if this is happening.
