Kill Captcha campaign

In a similar vein to that suggested by rorz0r, it would be easy to generate a random question , say some simple arithmetic, which would require some simple logic to answer. If the question was presented as a picture rather than text, it would not be easy for a spambot to enter the site.

Would that be readable by the user's software? And what about all those people who can't do simple arithmetic?
 
Offer a better solution or gtfo I say. Also, google's recaptcha brings actual benefits too (OCRing books).
 
There are already captcha farms but no need to pay anyone. Many less than legitimate sites have captchas for cracks/downloads/porn/whatever that redisplay captchas screen grabbed from legitimate captchas then someone else fills it in and the bot software submits the same answer on the legit site.
 
One a site I recently used the captcha was a puzzle where you had to match 2 or 3 pieces to a simple picture of a object, was easy to use.

I've come across that a few times now. It's pretty cool, and easier than some of the captchas where you can't make out head or tails.
 
As briefly alluded to in one of the posts above, captchas are an absolute nightmare for disabled and, particularly, visually-impaired people -- in addition to being widely hated by the majority of internet users in just about every survey ever conducted. There surely has to be a better way....
 
Tell me this - why make the text so hard to read?
Wouldn't a simple image displaying a simple-readable text work just as well?

I'm no web dev - so hence the question.

Then suggest one.
 
I've got something like this going on:

On site load ajax call for a token
when the user selects the last input box I do another ajax call with the token to get another 'password' for the submit that gets allocated to a hidden field.

On submit that password field must match the token and backend site password else we assume it's been auto filled. There is also a wait time between creating the token and being allowed to make the request for the password.

Sure, bots will find a way to auto complete this type of thing but it's unique enough solution to go under the bot programmers radars (and the timed delay between token and password would help prevent the signup damage).
 
Captchas are terrible, but what's even worse is having an army of spambots getting through because your "random question" isn't really random but always the same.

No. It has to be dangled. Spam bots, or the scripts/software can read regular font far to easy.
 
I have no problem with the CAPTCHA service, never had a problem with people complaining about it either. We also utilise honeypots and other related services. The only spam getting through are those done manually.
 
I've been researching ways to implement spam fighting techniques that don't involve a CAPTCHA and came across this article (http://nedbatchelder.com/text/stopbots.html).

The one twist I would add to this is implementing a CAPTCHA that acts as a honeypot. That way users don't have to deal with CAPTCHAs and bots will try solve it rendering their attempts useless.
