It has a rapid response to spam, but it times-out rather quickly, so
there are plenty of IPs that I'd want to keep blocked, that spamcop
has already timed out and put back on the streets.

We use a spamcop entry to add significant contribution to the
spam-rating factor, though not enough in itself to cause outright spam
blocking (but see next para)

I wouldn't recommend blocking on spamcop alone; but ACLs make it easy
enough to block on an IP which has an entry in spamcop _and_ an entry
in one of the technical open-relay blacklists, and it's extremely rare
for that to block a bona fide mail.
