Yes, I know. But if the cookie id of affiliate sites is installed in client-side through some cheating methods, such as cookie stuffings. Although actually the client didn't click the advertisement, the cookies have already been installed in client browsers. I think this is unethical and hurts the profit of company. How to automatically recognize whether the site does any cheating things?
