C-R *is* spam.  Interestingly, proponents use the same argument for it
that spammers do.  It works for them.  Spammers feel that .0001%
response is reason enough to load the rest of us with with work for no
pay.  Proponents of C-R feel that reducing their spam load justifies
having the rest of us work as their spam filter for free.  It's the "I
got mine, Jack" mentality which is sadly way too ubiquitous.

Personally I think that the answer to this problem is to simply reply
automatically to these challenges positively no matter what.  Puts the
job of filtering spam back on the first person.
