README.txt in Spam 5

Overview:
--------
The spam module is a powerful collection of tools designed to help website
administrators to automatically deal with spam.  Spam is any content that
is posted to a website that is unrelated to the subject at hand, usually in
the form of advertising and links back to the spammer's own website.  This
module can automatically detect spam, instantly unpublish it, and send
notification to the site administrator.
