I don't believe that. I don't believe C/R is the wave of the future
either, it's proven pretty inadequate thus far and flaw-ridden (I know
*I* usually throw away challenges even from well-meaning people.)
I can't know based solely on the challenge if someone is spamming me due to
a post I've made to a mailing list or the like, or if they're spamming me
because they're receiving spam themselves which forges my address as the
sender. So, generally, I'll answer the challenge. That way, I help make
sure that they get whatever message they're so concerned about, and can at
least hope that one challenge was enough to get me exempted/whitelisted
from any others.
Then I firewall the sending network, because unsolicited and substantively
identical (bulk) challenges are spam just like any other spam.
