It doesn't need to be available. If C-R gains enough popularity, of course spammers will figure out how to auto-respond to challenges. It's completely trivial to them, and it's well known that spammers will be to great lengths to ensure they reach the greatest number of people. If they don't do it now, it's only because so few people use C-R that it's not worth their bother. Plenty of people on these lists have admitted to, and in fact encourage, ignoring challenges. I know I've intentionally discarded them before, and I try to seed my Bayesian filter to recognize them as the spam they are. -- You win again, gravity! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
