Learn them as spam. That will tend to eliminate that effect.
Been doing that (learning them) for quite a while. I've had that
mechanism set up for several years now, and it's working fairly well
(after I adjusted the scoring upwards for bayes rules).
It appears to me that the hidden text is being randomly generated. Even
saw a random function of some sort in there. I presume it's been
designed to 'poison' bayes by vitue of the random text (and a sizable
amount of it).
Thanks.
