As you mention, it's absolutely useless for those browsing with large print, or even dyslexic users who can read plain text but can't decipher captchas. Also, it requires the user being able to either remember the address to type in, or to copy and paste it, because it can't be directly followed. And, well, having to contact a human for assistance just slows things down, not to mention that there are some potential security issues involved as well if you're registering a new account... And the sad thing is, you're required to decipher a captcha for every group registration on Yahoo Groups. I mean, yeah, group spam can get bad, but even then there are ways to prevent spammers from coming in without having to use a captcha (e.g., moderating every user's first post, a technique used by a number of mailing lists I'm on).
