I'm looking for someone that can professionally program a "Ad Click Spam Protection" script that can be added into any PHP website. NOTE: To filter out all the bot bidders, please solve this captcha here ''4+11 = ?' in your bid description (All bots will receive a one-start bid rating)... (Budget: €30 - €250 EUR, Jobs: Fraud Detection, JavaScript, MySQL, PHP, Web Security)
