I suspect the decision to start blocking SMTP had little to do with
bandwidth. Spam is pretty low bandwidth...even when sending thousands of
messages. The other problems it causes is the real issue... complaints
from customers, complaints from other ISP's, getting blacklisted,
getting sued.....

But yea it wouldn't be hard to track down offenders. I also think
filtering is cop out.
