It's pervasive because its profitable. It's been profitable because even a few weeks
of a high-speed circuit can generate millions of messages which don't need much of a
response rate to generate revenue. The problem now is that a growing percentage
of spam is originating from distributed farms of broadband connected users
(Commtouch says 80% in one article, but I'm not yet convinced its that high -
<http://www.clickz.com/stats/big_picture/applications/article.php/3337751>)
This would suggest that spam is pervasive largely because of the large number
of insecure systems available for origination (via port 25 :-), not because of
providers failing to close barn doors after the fact...
