Many of us receive dozens of spam messages daily.
Most of us get spam every day. Some of us get a little, and some of us get a lot, but if you have an e-mail account it is always there. For example, this morning, here's one that came to my inbox:

    Subject: Adobe

    Suppose we tell you that you could really lose up to 82% of your unwanted body fat and keep it off in just a few months, would you be interested? We certainly hope so! Please visit our web site - Click here!

Obviously this is spam, yet it made it through the spam filters and I opened it because the subject line made it unknowable whether it was spam or not.

Spam is incredibly annoying, especially in large quantities. If you have a public e-mail address you can receive hundreds of spam messages for every legitimate message that arrives. Even with good filters, some of the spam makes it through. And filters can sometimes delete messages that you really do want to receive. Spam is free speech run amok.

Where does all of this spam e-mail (also known as "unsolicited commercial e-mail") come from? Why is there so much of it? Is there any way to stop it? In this article, we will answer these questions and many others as we take a dive into the sea of spam.
