Prior to describing what spam filters are and how they work, you really do need to appreciate what spam is all about. You may have heard the term spam, but never really determined what is meant by the word spam.
In the simplest of terms, spam is akin to the junk mail that used to populated mail boxes in the brick and mortar world. Spam really is junk email.
Initially, during the earlier days of the Internet, spam was pretty harmless … irritating, but harmless. There are now some pretty rigid rules and regulations banning most types of spam.
In time, spam became something more than irritating in many instances. Spam became a vehicle through which those people intent on committing identity theft or ID theft could and did further their crimes. These people would send out spam emails -- broadcast emails to a wide range of different people. These emails were designed to entice people to provide personal and financial information to these crooks.
Oftentimes, these spam emails contained fake advertisements for products or services that are appealing. Other times these spam emails were purportedly from a person’s bank or financial institution -- or even from an Internet Service Provider. In any case, these spam emails contained content designed to elicit personal and financial information from people. |
