Then the ISP is obviously either incompetent or deliberately aiding the
spammers. Why should you even consider anything less than blacklisting
every netblock the ISP has?

What do you do if the ISP says "We want to turn them off, but they've managed
to get a restraining order preventing us"?  We've seen THAT before....

Then the part above about

obviously does not apply. They are responding. You clearly do not even consider
blacklisting them.

You might ask them for help in blacklisting exactly the spammer's addresses.

All this sounds very nice. But:

If the only way to contact SPEWS is via postings in a newsgroup, an
ISP may find themselves unable to make any meaningful response (there
are issues of customer confidentiality, business considertaions, a
whole lot of reasons that an ISP might not wish to discuss the alleged
wrongoings of one of its customers, the measures which it has or might
take or the details of contractual relationships or legal advice they
have received. So all of this is really irrelevant to the topic at
hand. 

An anonymous group using unknown criteria, however well motivated, is
not useful. And any mail administrator who uses their lists is, in my
opinion, a fool.
