Just curious tedd, but what do you mean by "CAPTCHA's show the world
that you really haven't thought this out". If you have a better
alternative I'd love to hear about it.

I claim that for most web sites, they don't need a CAPTCHA -- so why
use one? CAPTCHA's carry a lot of accessibility baggage.
There are many of high profile sites that don't use CAPTCHA (i.e.,
Eric Meyers, Chris Shiflett). Instead they have developed other
methods, such as attending to their sites and monitoring post.
I concede that if an evil-doer wants to make things hard on you by
automated posting, then it's an uphill battle that can be effectively
fought by using a CAPTCHA. But I claim there has to be a better way.
While I've been working on the problem (on/off) for several years, I
haven't found an acceptable solution. Of course, better minds than
mine have tried and failed, but I always think that I might do better
-- a flaw in my personality, I just don't know any better.
In any event, I've approached on the problem from two sides:
1. To create a CAPTCHA that would be difficult for automated systems
to break but easy for the user to navigate -- my Arrow CAPTCHA is the
best I could create. However, I'm sure with a little effort from
someone like you or Rob, it can be broken.
In addition, my arrow CAPTCHA is for the sighted and that leaves out
a lot of people. My Audio CAPTCHA works well for the blind, but that
too can be broken.
2. To create a server-side method that monitors who's making the
post, frequency of the posts, and content of the post before allowing
the post. While I'm not finished, this is something that I continue
to work on. I think that direction shows the most opportunity for
success.
So, when I say "CAPTCHA's show the world that you really haven't
thought this out", that's what I mean. I still haven't thought this
out either. But I think there'a better solution and I'll keep working
trying to find one.
Cheers,
tedd
