Some time ago, I was amazed by the difficulty of a CAPTCHA implemented by rapidshare. Well, today I came across one which is even worse. We all know that using a CAPTCHA is very bad on a usability point of view, but without them, spammers would easily add junk in your database. But it's even worse when the CAPTCHA software is not working properly...
Sure you won't get any spammers here... nor regular users.
Just to avoid confusion or misinterpretation, even if you refresh/clear cache/etc. you will get this message. And no, 'ERROR' is not the solution of the CAPTCHA. Hope that phishtank will fix that soon...
We see many different CAPTCHA on the web, some are good, some not. I do not know why people keep developing their own simplistic CAPTCHA when there is a good services line the one provided by reCAPTCHA. This CAPTCHA is pretty solid and also adds audio version (way better for accessibility).
