Then the Bayes filter is not working correctly.  It is not a "word
filter" in the sense of the old Outlook Express mail rules.  There are
some great explanations of how Bayesian filters work on the interenet
that are much better than anything I could type up here.  You should
understand that information if you want to know why bayesian filtering
is such a useful tool ... at least for now.

Having said that, there are a lot of little tweeks that need to be
done to make a bayesian filter work well.  Mine has never gotten a
false positive, but that is because I have the threshold set
relatively high, and so have more spam get through.

Until they use C I A L 1 S or other manglings that you can read but
slide right through your word filters.  It is an ever escalating
battle.  We come up with new tools to protect us, "they" come up with
new ways around the tools <sigh>
