Police in London have begun utilizing banner ad technology to warn visitors of illegally pirated content. These banners appear in the usual place of paid adverts and flash messages, such as: “This website has been reported to the police. Please close the browser page containing this website.”
The idea is to prevent such sites from gaining revenue through internet advertising. Currently, copyright-infringing websites make inordinate amounts of money through advertising. These warnings make pirated sites look much less authentic to users.
