You can easily filter SPAM, the difficulty is not removing valid
messages along with it. That is what you will never know about the other
lists. Filtering is done based on certain keywords but there is always a
chance that a good message will contain the same keywords.
For instance, a valid message that someone is giving away FREE Vanagon
parts might be excluded bacuse of the word FREE.
