Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A click farm is a form of click fraud, where a large group of low-paid workers is hired to click on paid advertising links for the click fraudster (click farm master or click farmer). The workers click the links, surf the target website for a period of time, and possibly sign up for newsletters prior to clicking another link. It is extremely difficult for an automated filter to detect this simulated traffic as fake because the visitor behavior appears exactly the same as that of an actual legitimate visitor.
