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?

The objective isn't just to stop that spammer. If the ISP is clearly
acting irresponsibly and not dealing with a spam problem, getting them
to wake up is more important than the individual spammer.

Not if its the only way to wake up that ISP.

Of course, this sort of block must be a last desparate measure. At
a minimum, the spammer's been at it for weeks and you've mailed abuse@,
postmaster@ and the whois contacts without eliciting a response from
the ISP, before you even consider it. 

Even then, you should likely try phoning the ISP and/or browsing
their website for other contact addresses before taking such a
drastic action.

But if drastic action seems the only way, don't stop at half
measures. Blackhole every netblock they have, and for all
packet types, not just email.
