But I guess content filtering can be used to blacklist spammers by

the more likely that a false positive will block somebody you didn't want to
I've run into a few domains that run local blacklists that forget to to leave
some way to get in contact with them so you can tell them that you're dropping
50 of their users because their mail is bouncing because their filter can't
tell the difference between spam and a mailing list....
One thing often overlooked when designing things - the designers and early
