‘Human Input Validation’ (also know as CAPTCHA) not only harms usability, but breaks anti-discrimination laws in many countries. In addition, recently spammers have begun to use tactics that defeat the process.
Many websites using forms now show an image of some text which the visitor must enter into a textfield to proceed. The purpose of this is to stop automatic form submission by computer programs, which may be malicious.
It is not just computers that find the text difficult to read — visitors with visual impairment will also be unable to fill in the form. This is not only inconsiderate; if the form is on a business website, this is illegal in many countries (for example, in the UK it would be illegal under the Disability Discrimination Act 1995).
This is a serious issue. Please help me in reporting all web sites that use CAPTCHA to the proper authorities.
