Ah!  But then the ISP knows which users are spamming everyone else since
they can easily tell that by the load put on their email servers.  They
can then cut off service for that user and let them know that either
their systems have been compromised or that they have violated the ISPs
usage rules by spamming.

End result is that spam gets stopped and fewer compromised systems left
to run on the Internet.

Be careful how you get yourself involved with persons or situations that
can't bear inspection.
