If the mail delivery path is "spammer -> forwarder -> isp ->

"spammer-pretending-to-be-a-forwarder -> isp -> recipient" then the
only useful place to send it is the ISP, but sending it to the
spammer as well has no real cost.
Problem: if the ISP gets the report and doesn't know that the
forwarder is legitimate, it will damage the reputation of the
forwarder.
I might have missed a suggestion to not send it to the ISP, only to
the apparent forwarder, when there was something that looked like a
forwarder - if so, don't do that. :)
Not "looked like" but "was verified by the user, by the server sending
a magic message to the user-supplied 'this is my other address' and
seeing it come back from the forwarder".
