Is Bayes Dead? Have the spammers won?

[Marc Perkel]

Maybe I'm doing something wrong but with the various methods of bayes 
poisoning going on I've found that bayes is just lowering the score of 
spam and causing more spam to get through. Where bayes used to be the 
centerpiece of spam filtering now I have turned it off to increase accuracy.

Anyone else seeing this or is there some new tricks that I'm missing out on?
