II. Moving forward: Social trends
Social trends: spam
Millions of people receive dozens of unsolicited commercial e-mails (UCE), known popularly as spam
E-mail addresses posted on Web sites or in newsgroups attract the most spam
Spammers use software harvesting programs such as ÅgrobotsÅh or ÅgspidersÅh to record e-mail addresses listed on Web sites
They crawl personal Web pages and institutional (corporate or non-profit) Web pages
Newsgroups can expose to spammers the e-mail address of every person who posts to the newsgroup
