It's a predictable response by the spammers. Did anybody really expect
the spammers to go "oh, well, that's it, we'd better shut up shop
now"?

I'm an advocate of SPF, but not because it's the magic bullet that
stops spam. It does however allow innocent domains to say "no, I
didn't send that" and thus avoid the double-bounced backwash from a
spammer forging their domain as the sender.
