It all comes down to the purpose of captcha. It is a cognitive test by
supplying a puzzle that would be difficult for a computer to solve to
try and prove you're not a bot. Today there are very few of those kinds
of puzzles. Image and audio recognition are about the only two that
haven't been cracked and it's turned into an arms race. Eventually the
algorithms will be sophisticated enough that they will either mimic
human behavior undetectably or the cognitive load to solve the captchas
will increase to the point where real people can't solve them (already
happening). Either scenario ends badly for those trying to protect the
integrity of their content sites. In the meantime, just saying the
current stuff doesn't work doesn't help because nobody has come up with
a better solution. Anything that lowers the puzzle difficulty also makes
it easier for the algorithms to solve.

Guys,
I am fed up of audio captcha. My Member of Parliament currently has a
question in to the UK Prime Minister about use of audio capcha on
government websites. I know it's a drag, but we need to challenge
these things every time we come across them. I was on a site the other
day which had a simple equation instead of an audio captcha. It was a
joy.
BTW, I love the bit where it says the audio captcha is to test whether
or not you are a human being. I always write to them saying that,
despite the fact that I can't see, I am nevertheless a human.
Cheers

I find that rather interesting. now why would the general public (and business
professionals) get the impression that mozilla was the most accessible web
browser for any OS? sure it works well with windoweeyes and jaws in the windows
platform. it also works mostly with orca in linux. it does not work at all in
OS X with voiceover (and I have even tried growl with it and still had a lot of
issues).
I have sent more than a few emails over the last few years and all I get back
is nothing but a load of crapola and finger pointing. now I know we can't
prevail upon a bunch of volunteer code monkeys and still have them do the work.
if they were paid and we wrote the checks, that would certainly be a different
case.

loads of programers think firefox is the most accessible browser out there. They
get shocked to find it does not work on the mac. I recall a programer at my work
insisted that I should use mozilla. Only after he tried using it with vo by him
self, was when the message got across!
