I checked in some changes to reduce the overlap in the FRNAME rules. The 
reason they are scoring that high even with overlap is those are strong 
spam signs in the masscheck corpus.

And: Bayes and TxRep did exactly what they are supposed to do here.

   Justice is justice, whereas "social justice" is code for one set
   of rules for the rich, another for the poor; one set for whites,
   another set for minorities; one set for straight men, another for
   women and gays. In short, it's the opposite of actual justice.
