I think you're *nuts* if you think an ISP should be held entirely
accountable for its customers actions.

I'm one of a handful of administrators in a small ISP, and we do our
damnedest to ensure that everything runs smoothly.  We have a fairly strict
AUP that we actually enforce, we do egress filtering (not enough, but we're
working towards it), we contact customers that are infected with virii and
worms, and we have *zero* tolerance for script kiddies (usually instant
blackholes).

IMHO, that is about all you can expect an ISP to do.  Have an AUP that
incorporates all of your problems (spam, abuse, viruses, etc), and enforce
it.  You can *not* expect the ISP to police absolutely everything that its
customers do.  You can *not* expect the ISP to be held responsible for three
of its fifteen thousand customers browsing child porn.  You can *not* expect
the ISP to be accountable for its two hundred script kiddies.

You *can* expect the ISP to have an AUP.  You *can* expect the ISP to react,
and to react quickly.  You *can* expect the ISP to co-operate with the
proper authorities, if it goes to that level.  You *can* expect the ISP to
contact and work with (when and where needed) other ISPs to track down and
solve problems.

I am a Network Admin, and I am *still* looking for an effective way to block
outbound spam from our customers.  I spent two months purging all our mail
servers of FormMail, and scan them every night for more vulnerable versions.
Do you think that I should be sued because one of these slips through the
cracks (there's a 24-hour window in which one can be installed and abused),
and you get some porn spam?  I certainly hope not.

Being able to sue ISPs for their customers actions is pure insanity, and
will just lead to massive ISP shutdown world-wide.

However, being able to sue ISPs for *negligence* and for *ignoring*
customers actions is a whole different boat, and I think is an idea worth
looking at.

Administrator.  Strung out on caffeine, because I spent most of last night
hashing out some more details on our anti-spamming actions.
