Expiry is important because we don't want every domain name ised as
a throwaway to be poisoned forever.
Why not?
Unless a domain is unused for a year it seems reasonable to
assume it is still owned by a known spammer. So why expire
it?
Because otherwise the BL would actually have to check the domain
on each query about it to make sure it hadn't changed owners since
the last query -- or else risk screwing a perfectly innocent party
who just bought the domain not knowing of its history.
