Hello Jim and everyone,
Read the archives. There are other utilities to control spam bots some
of which require no interaction from the user. Again read the list archives.

Hey Everybody,
Steve, I'm not at all sure I get your point.
You seem to be saying that people who set up ways to gather user
generated content are responsible for policing it. Perhaps, but then
again that's what captcha is, a way to police user generated content.
You say that you're sure your bank has really easy to solve captchas.
I don't know anything about that, but I rather suspect they have some
good way of keeping bots from trying to guess their member's
passwords, and I'm guessing that includes some kind of more difficult
captcha. As I say though, this is totally supposition.
You say that Captchas are a lazy solution to this problem. In fact,
captchas are an excellent solution to the bot problem. One way I
know they're a great solution is that the computer can't read them,
much less solve them, for us blind folks.
I know that captchas suck for us, and I'd love to see something better
come along. However, so far nothing has come along that does as good
as job as captchas do of automatically telling if you are a human
being, capable of picking patterns of color or sound from a complex
background, or a bot who is not capable of these things.
For a long time I've felt that technology will catch up to the
captcha. I'm pretty sure that a cloud based captcha solver,
accessible to the public, will be available in the next few years.
Until that happens though, we're going to have to rely on readers,
audio captchas, and customer service desks.
Take Care,
Jim
