From Chapter 2: Botnets Overview of Craig A. Schiller’s Botnets: The Killer Web App (Syngress: 2007):
Dollar-Revenue and GimmyCash are two companies that have paid for installation of their Adware programs. Each has a pay rate formula based on the country of installation. Dollar-Revenue pays 30 cents for installing their adware in a U. S. Web site, 20 cents for a Canadian Web site, 10 cents for a U.K. Web site, 1 cent for a Chinese Web site, and 2 cents for all other Web sites. GimmyCash. com pays 40 cents for U. S. and Canadian Web site installs, 20 cents for 16 European countries, and 2 cents for everywhere else. In addition, GimmyCash pays 5 percent of the webmaster’s earnings that you refer to GimmyCash.
