True, but many ISP business cases are based on not having to identify
the individual user (e.g. public access Internet in various restricted
areas), so they try to get away with what they can.  People are aware
of how spam works, so by easing spamming they kill their own business.
Of course, anyone in the know can spam or inject SQL worms anyway, so
SMTP authentication will not prevent spam perfectly, nor would
requiring identity cards of everyone using the Internet everywhere
solve the SQL worm problem.

But maybe we are drifting off-topic...
