Whats to stop people from clicking their own affiliate links repeatedly?
As is the case with other advertising agencies, our system does its best to guard against this. We log agent IP data for each clickthrough, and ignore redundant traffic. Additionally, we routinely skim the logs ourselves and watch for artificial-looking clickthroughs. If you notice anything suspicous, like a multitude of clickthroughs coming from very similar IPs, please let us know.
