Not  sure  if  I  understand--a subscriber to a list does not have the
ability  to  relay  to anyone but other list subscribers. On the other
hand,  any non-confirmation list server (like IMAILSRV) can readily be
used  to  subscribe  remote  addresses  to  a  list without the remote
recipients' consent, and thus provide a more robust hijacking method.

Declude  Hijack  would  be  a  potential treatment for such abuse, but
other   anti-spam  measures  would  probably  prove  insufficient,  as
intelligent  spammers will not use already suspect systems to initiate
new  blasts. The best treatment is double-opt-in only, as you get with
Declude Confirm or any other list manager.

I  agree  fully  that  anyone  supporting spammers should be punished,
including  ISPs  who choose to look the other way instead of realizing
that  the  ethical  rules  of  providing bandwidth have changed. While
meeting SLAs is still paramount, AUPs are increasingly important, even
if the latter may mean lost business.
