Spamming

It's very likely that every time you check your email account, you will find some unsolicited ‘junk mail’, or promotional or advertising material that has been sent by a business or organization. Unsolicited electronic mail, also called "spam," is both a nuisance to Internet users and a threat to network security. Spam imposes substantial costs on Internet users and providers (especially in terms of time), and users and Internet providers have undertaken a variety of measures to reduce or stop spamming. Later in this unit (when we look at how website owners should comply with data protection laws), we will see that most attempts by users to control spamming have been counterproductive.
