You are quite right. Thank you.

I found some ways of showing several issues to be revenue-tied, such as
blocking port 25, etc. This issue is something I am at a stage of
exploring, and like it or not.. network operators are the ones who deal
with this (on whatever level they do).

I am unsure of where else to go with this, and if some ISPs do something
for now, that is a step in the right direction until a better way shows
itself. Whichever way we discover, for now, raising awareness is all I can
think of.

On a sarcastic evil tone, we may just plan to release a "fix" worm to
harden all these devices world-wide. Right! Because that worked so well
for us before. :>
