send X-Advertizement to /dev/null

Just feed up with junk mail. I have yet to have spam domains honer their
list removal request and they do not listen to compaint mail.

I want to put all X-Adverizement e-mails to /dev/null. I do not want to
even bouce it.

Any ideas? (Yes, I do have /etc/procmailrc files on my system)
