URI based black lists have been extremely effected in
identifying spam.
I propose another kind of black list. A list of email
addresses embedded in the message body as replies to nigerian
type spam and other spam where you are instructed to reply to
the email address in the message body.
One thing about all spam is that the spammer wants you to do
something.
And it's what the spammer wants you to do that is the key to
identifying spam. Most spam wants you to click on a link. So
the URI black lists work well because it catches the sites
that spammers link to.
But - a lot of spam - like nigerian spam - wants you to reply
to an email address in the message body in order to do what
the spammer wants.
So if there were a blacklist of email addresses that spammers
use as the place to reply then that would cut into the
remaining spam significantly. If we can block email based on
a real time list of email addresses within the body a whole
new class of spam can be blocked with very high accuracy.
Who likes this idea?
This has been discussed many times, even on this list. I'd recommend
searching the archives and reading the thread on it first. The only
problem I have with it is that it would be very manual, and address
rotation per msg would be very easy to defeat this.

<<jdow>> Directly answering his question - it is not infrequent these
days for the "answer" site to be part of a botnet, I understand. So a
blacklist would have to be bigevil.cf in size and then some.
It'd be easier to simply click fraud the sites until the vendors who
commission the spam catch on and turn off the money up front.
