Just curious on the conventional wisdom whether Captcha is required in Flex desktop web applications, or if something inherent in Flex/Flash plug-in means that bots in the web cannot auto-complete user login forms (e.g. username and password) or other forms. I haven't really seen too much for Captcha type components in Flex (is it unnecessary)?
Currently my user login requests an email and password, and for new accounts, requires the user to click on a link to validate his or her email address before registering that user as a valid person. Is that sufficient?
