*sigh* Does your experience as a user counter mine as a postmaster of an
entire domain for 6 months? Where I monitored a system that moved, I would
wager, 100k messages per day? Did you have a filtering system on said domain
in place that blocked 5-10k spam per day?

That is not how a spammer operates. Getting a leased line set up costs a
few hundred dollars. Even a cable connection costs a good $100. Why set
those up when they are going to be shut down in about a day. It is not
profitable. They get an account at the large national providers with bogus
names and send spam out through open relays. They cram as much as they can
through before they are shut down. When that happens, the get another account
elsewhere and continue. You can get dial-up connections about once an hour.
You'd be lucky to get ISDN/DSL/Cable/Leased line/Etc once a week.

No, it confirms that each run they change the address. The spam that I
see across my personal accounts and the several work accounts are often sent
out 2-3 times because of duplicate addresses in the list. Some have different
from addresses, some don't. Those that do only have software that changes the
address every run or every few thousand addresses. Incidentally, the 10-20
pieces I see per day across all my accounts, very few are directly addressed.
Please, just trust me on this. While you're talking your experience I am
talking about my job for 6 months and my continuing involvement in the
industry spammers exploit.
I had to, and do know how spammers operate, what the technical side of
the matter is, what measures are being taken and the relative strengths and
weaknesses of each.
