Spam FilteringThe European Union's Internal Market Commission estimated that "spam" cost Internet users €10 billion per year worldwide. The California legislature found that spam cost United States organizations alone more than $13 billion in 2007, including lost productivity and the additional equipment, software, and manpower involved in combating the problem.
Spam's direct effects include the consumption of computer and network resources and the cost of time and attention in human resources spent dismissing unwanted messages. In addition, there are opportunity costs of those who forgo the use of email-afflicted systems, as well as the indirect costs borne by the victims—both those related to the spamming itself, and to other crimes that usually accompany it, such as financial theft, identity theft, data and intellectual property theft, virus and other malware infection, child pornography, fraud, and deceptive marketing.
