score BAYES_50  0  0  2.0    0.8

not that I disagree with this score, but it does not have 0 score...

I was thinking 0.001 informative, like BAYES_20 and _40 have. My error, 
apologies.

I'm surprised that "insufficient data" is biased towards spam, but perhaps 
that's based on an assumption that a properly trained Bayes will reliably 
detect your regular hammy message traffic and anything it doesn't 
recognize is therefore probably a new form of spam it hasn't been trained 
on yet.
