If you participate in affiliate programs, one problem that you may encounter is that other people may remove your affiliate id from your advertising campaigns. They do this so as to substitute their affiliate id for yours (and "steal" your commission), or because they incorrectly believe that must pay more for products that you refer as an affiliate. This script prevents this problem, and is ideal for serious affiliate marketers. It is easy to use and setup and can protect an unlimited number of affiliate links.
