[SpamCop-List] Comcast, etc.

[Stephen Bye]

Forgive my naivety, but what's the deal with companies like Comcast and 
Kornet? Do they deliberately sign up spammers, or do they kick themselves 20 
times a day, saying "Damn! We fell for it again!"?
Does any "real" e-mail ever come from them, or is it practical to just block 
the whole domain?
