Description Marc Perkel 2002-06-24 18:51:24 UTC 
I think the rule "for free" catches to much non-spam. I think it could be
improved by requiring that the F in FREE be capitalized. I think most spam will
say "FOR FREE" or at least "for Free". Non spam will use "for free".


body FOR_FREE			/\b(?i:for) F(?i:ree)\b/
describe FOR_FREE		No such thing as a free lunch (1)

The new one does do a bit better than the old one on my corpus.
