Um, I have.

It averages about 250 subscriptions a day, and 100-150 unsubscriptions.

I'm averaging about 40-75 dead addresses on each update, and I update
from the error logs 2-3 times a week. Those unsubs are included above.

Lessee. 90% of the users are digests, we ship ~20 messages a day, and
about 10 digests a week. I do know that if I don't update the lists,
within a week, it's generating ~15-20 megabytes a day in error returns
at the minimum.
