Hello,

I'm currently implementing a small adsense clone using PHP and javascript, I would like to know how to prevent click fraud. I already tought about :

1) Ip tracking so that the publisher gets caught if he clicks its own ad (easy to bypass) and for ips clicking on the same ad more then once in a short time frame.
2) CTR % -> Can give red flag.
3) Delay between page load and click
4) ??

I need your thoughts about this points.. and new ones.

tks
