That is a fair question, indeed.
OTOH, tempfails would probably have been noticed only by a very few, as
it would "only" have delayed emails for two hours.
Two days would have made a difference here when delivery queues would
start to get filled up.
Do we have positive knowledge that the Manitu/Nixspam folks are
subscribed to this list, too?

It'd nonetheless be interesting to know whether this was "just" an

If they don't want to operate the list anymore and let admins know that
the hard way, why don't they just remove the DNS delegation for the
zone?
That might create tempfails if the MTAs are configured that way, but
not rejecting legitimate mail.
