Spam Bam, No Thank You Ma’am

(See the "How to Read a Privacy Policy" sidebar in this chapter.) Or a friend might have signed you up at one of these sites (friends like this you don’t need). More likely you were the victim of a “dictionary” or “brute force” attack, where a spammer overwhelms your ISP’s email server with messages sent to random combinations of letters (like , , etc); those that don’t bounce back are added to the spammers’ collection and then sold—over and over and over.
