From: "Marc Perkel" <[EMAIL PROTECTED]>
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.
Well, Blue had something of an idea. It was simply carried too far.
As you observe every spam email contains at least one URL that is
important. It should be possible to cull the one URLs that are
important to the spammer from a list of other URLs. (A list of known
good sites would help this.) Then you use a tool that mimics browser
behavior to connect to each of these sites. If the spammer gets
paid by detected traffic on the actual advertisers web site then
this will generate a lot of spurious income for the spammer and
"detected fraud". This should pretty much cut off the spammer's
income source, except for the vertical market spammers like Leo.
Instead of freezing them out pull Google Click Fraud on them.
