And of course makes it impossible to be heard if you don't have web
access, which is the case for some folks behind firewalls, connected by
non-IP networks, etc.  I haven't visited the site, but -- does the C/R
mechanism work with the browsers used by the blind?

More generally, challenge-response is a highly-hyped but
highly-inefficient and easily-subverted anti-spam mechanism.  As I've
pointed out elsewhere, it's pretty easy to get around a lot of C-R, and no
doubt spammers will do exactly that if and when it becomes more prevalent.
It's just another ineffective snake-oil "cure" for the symptoms of spam,
and like most of the others, it does NOTHING about the disease.
