Unfortunately spammers can create email addresses very quickly, and
CAPTCHAs are inherently weak (even the best of them are easily cracked
by the Chinese human "botnets"). However, I wouldn't be against a
system of spam filtering with three levels: Not Spam, gets straight
onto the list; Definite Spam, gets deleted; and Dubious, which gets
dropped into a mod's basket.
