I can't see this without thinking of one of my favorite Dilbert
cartoons.  "But your e-mail address reveals your newbie identity.
You're probably a goat herder or a cartoonist".  At the time I
think Scott Adams address as .

If you want government to intervene domestically, you're a liberal.  If you
want government to intervene overseas, you're a conservative.  If you want
government to intervene everywhere, you're a moderate.  If you don't want
government to intervene anywhere, you're an extremist -- Joseph Sobran

So far, I've found 2 things that I could have done (and am implementing
today) to identify this issue:

   - Watch for large volume increases coming from accounts. This account
   had a 5x increase.
   - Watch for accounts cycling through lists. We hadn't built this before
   because it's a time consuming process for a user to remove and then
   re-upload a list and the lists are small. This user was cycling through
   many lists of 800 recipients.

I can see why our existing systems didn't catch this one though -- open
rates were good (20-36%), complaints weren't too high (.1% - .19%), bounces
were minimal, domain distribution was normal with a large portion of it on
domains with feedbackloops.
