I was wondering if there is anyway you can block or exclude people from submitting multiple fake ip's online . For example I have a google pay-per-click campaign set up on adwords. I downloaded a program in minutes which enabled me to hide or give out a fake ip address which also allows you to use a different ip each time. I tried this out on my own link on google which in turn got through adwords and I was charged for the click. My question is how would you be able to counter or block someone who continuosly clicks on your link with a different fake ip each time?
