Why Am I Getting All This Spam?
Every day, millions of people receive dozens of unsolicited commercial e-mails (UCE), known popularly as "spam."

- USENET newsgroups -- Newsgroups can expose to spammers the e-mail address of every person who posts to the newsgroup. Newsgroup postings, on average, generated less spam than posting an e-mail address on a high-traffic web site. In our study, we discovered that most newsgroup-related spam is sent to the address in the message header, even if other e-mail addresses are included in the text of the posting.
- For the most part, companies that offered users a choice about receiving commercial e-mails respected that choice. Most of the major Web sites to which we provided e-mail addresses respected the privacy choices we made -- when a choice was made available to us.
- Some spam is generated through attacks on mail servers, methods that don't rely on the collection of e-mail addresses at all. In "brute force" attacks and "dictionary" attacks, spam programs send spam to every possible combination of letters at a domain, or to common names and words. While these attacks can be blocked, some spam is likely to get through. In many cases, spam generated by these attacks will be directed to shorter e-mail address (like bob@domain.com) before it is directed to longer addresses (like bobwilliams@domain.com).
