Has anyone ever collected statistics on which of our captcha images are most commonly entered incorrectly? I've noticed that some of our images are quite difficult to read and should probably be removed from rotation. I could imagine applying a heuristic like:
0-10% wrong: Delete - too easy 10-30% wrong: Keep - just right 30-100% wrong: Delete - too hard

Since when was a CAPCHA clear enough that it is rarely entered incorrectly a bad CAPTCHAs?

I'm fairly sure not, although you might be able to run those from the logs. I would really like to see a feedback mechanism in fancycaptcha (or all captchas for that matter) so we could automatically run those numbers.

Hello,
I am currently working on Multilingual and effective Captcha project for GSOC 2014 just to
encounter the same problem of difficult image I did proposed the solution as an indexing System
for image which will improve overtime by removing non user friendly images from those user
friendly, more detail about this image indexing system is discussed here:

Thank You
