We already know how to find spammers who use their machines to send spam. We
need to have a way to find spammers who abuse other's machines to send

You're clutching at straws. You can register domains without proof of
identity, and that's even assuming the spammers use a domain which they
registered for themselves, rather than some other domain which happens
to permit the machine which has been compromised.
