That doesn't work. Most people don't have a fixed IP address. It
just results in huge numbers of innocent users being blocked. It can
(and has) happened. And not just to customers of the Internet
Provider You Love To Hate.

If you look at the spam posted from IP addresses assigned to china,
most resolve as non assigned. That means they are squatting on blocks of
addresses with no legitimate users. Blocking those will not hurt anyone
but the spammers.

No, what you are referring to is just the fact that chinanet.cn.net has
purchased huge blocks of address space, but then not SWIPped them to their
customers... so in fact nobody has any clue whose space it really is or
what it is being used for, all you can tell is that it's in China. If spam
originates from that space, you can't figure out who to contact because
Chinanet is the only thing registered with the NIC. It's shameful.

If you actually see something coming from unassigned space, like Network 10
or 192.168, it's a sign either you've misread the headers or the header
line you're reading is forged. ONLY the top Received: line in the mail
header is believeable, unless your mail server adds more than one in which
case the top two might be. Anything else is provided by the site that passed
the mail to your server, which is sadly often a compromised PC.
