Did you include the bayes-filter into your forum?
I only implement the filter to my local installation. A lot of files must be changed manually that why I don't like to include the filter to my forum (without an official update).
Or in another words, have you a working copy and are you able to share first insights?
I ask, because the minimum time for request-to-sending-back of the posting form doesn't prevent spam postings in my forum.
But the implemented filters sees to work fine in your forum. All SPAM messages are flaggend correctly. The new bayes-filter works the same way. Based on trainings data, the filter flags the messages. At the beginning, the filter may works poor because no trainings data are available. The filter needs SPAM and HAM postings to learn the different (i.e. to calculate the probability of the SPAM level).
