The Spam module provides numerous tools to auto-detect and deal with spam content that is posted to your site, without having to rely on third-party services.
The Spam module provides a trainable Bayesian filter, automatic learning of spammer URLs, flagging of content with an excessive number of links, the ability to create custom filters, and more.
[UPDATE: 1.2 was not correct as some of the hooks would not get defined. More or less, that means some of the functionality would not work properly. Please upgrade to 1.3 to fix the problem. Seeand among other similar bug reports.]
IMPORTANT UPGRADE INFORMATION
When upgrading from version 6.x-1.0 to a newer version (6.x-1.x-dev or 6.x-1.1-beta which is to appear soon) make sure to DELETE your existing version before extracting the new version.
We changed the name of many folders and files and not deleting first will generate all kinds of problems that we're not interested to hear about!
Thank you for your comprehension.

The Spam module includes several spam filter modules, all of which work together to determine if a given piece of content is spam. Each module will review the content and return a score between 1 and 99, where 1 means there is a 1% chance that the scanned content is spam and 99 means there is a 99% chance that the scanned content is spam. The Spam module takes a weighted average of all of these scores and assigns a final overall score for the content. Based on this final score, the content may or may not be allowed to be posted on your website.
