The Statistical Spam Filter (SSF) uses naïve Bayes classifiers as a machine learning technique for automatic text classification. This technique can be used to filter out or block spam content.
SSF comes with a submodule that makes use of the service provided by SSF to prevent comment spam (see below).
The service provided by SSF can also be used by other modules to create their own spam prevention functionality.
