SP is biased in favor of avoiding false positives so this doesn't surprise me.  Glad to hear that 
combining filters works well.  Statistically it is impossible to catch everything and there will be 
occasional spams that include enough of the right words to get past.  I think SP's biggest weakness 
at the moment is that it does not extract enough useful tokens from images to block the image only 
spams.

All the best,
