I am setting up a web site and going to use “captcha” to prevent robots.
I get rather annoyed with some of the systems where you have to try and try again as the words are unreadable.
Therefore I am just going to use these letters/numbers
acdefhkmnpqrstwxyz 234578
This is in the hope that it will avoid some confusion (e.g. 1 and l).
Is there any other things that I should consider?
easier for humans, easier for robots…
think about visually impaired people, they hate captcha even more
why reinventing the wheel?
