Re: Example of accessible CAPTCHAS that work well

if we want to talk security and percentages - both I am qualified to do it
is a different list and nothing to do with accessibility.

An accessibility reasoning for a value judgement is short sighted and
misplaced when something is accessible according to the guidelines.

Denis - I think you made a odd statement - dump wcag 2 as it does not mean
something is accessible.  We all want a perfect world but denis as an
engineer i deal with realities and guidlines matter  - captchas are
accessible and meet guidelines. if you remove this what can i code to?

this is very simple and not complex.

cheers,
rob
