We seem to not be understanding each other.
The reputations are:
for feature in message.features:
reputation.Vote(feature, message.is_spam)
Not:
for feature in message.features:
if not message.is_really_really_really_spammy:
reputation.Vote(feature, message.is_spam)
And yes, as signals become murkier, it's harder to know what is spam and
what is not, our false positive/false negative rates will go up, and we
work to improve them.
