No, you're a CAPTCHA kook, and I'm an SPF kook, we got enough
kooks here.
I believe I have perfected my anti-spam system. Umm, well,
at least I can assure you that in my own mind the system is
perfected.
It's apparently more complex than "reject anything that's no
SPF PASS, and challenge any SPF PASS from unknown strangers."
As long as you don't send challenges to me for any SPF FAILs
do whatever you like. If your CAPTCHAs come as PNG you offer
that I can signup for a database for the blind. And finally
your memo claims:

So far they didn't give up to send hundreds of mails per day
to my Message-IDs, just an example. At least they gave up to
abuse them as Return-Path, either an SPF FAIL effect or luck.
Bye, Frank

I think we've seen that forcing spammers to send more spam
hasn't been an effective way to make them stop sending spam.
