[gui-talk] CAPTCHA is Frustrating; Solution Needed

[Rick Roderick]

Another problem is that the audio captchas are often not much use.  I am 
hard of hearing, and I often find the audio versions so distorted that I 
can't figure out what is said.

Perhaps, an alternative would be the need to answer a simple question.  For 
example, write the following numbers in reverse order, 26791.  One would 
then write 19762.

Give a homonym of would, wood.

In the sequence, 2, 24, 6, 8, 10, what would the next number be?  Of course, 
the answer would be 12.

It should be easy enough that most people would be able to do it but done in 
such a way that a machine would be unlikely to figure it out.

Of course, convincing site administrators to use it would be another 
problem.
