 	Ah.  I see.  I think it is valid behavior.  (that's also why I 
don't use auth image, people make mistakes sometimes, and spammers easily 
beat captchas, so it is more of a burden on users than spammers).
 	I think the bayesian filter can be much better trained if it is 
allowed to train on the text of comments that other filters (hostblock, 
akismet, etc.) catch.
 	I'll check in my code anyway, and let you look at it.  I still 
think the pipeline should be run twice, but probably some filters have to 
use the $secondRun flag to do the correct behavior.
 	See the comment on line 209 and the block of comments above in 
bayesianfilter.class.php.
