Have you looked at our Contact Us page? It uses a CAPTCHA, which is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”. The test requires that a person filling out a form on the screen reads some obscured text in an image on the screen, and types the text correctly. They are designed to make sure that only a human, not an automated computer process intent on malicious purposes, is completing the form, based on the premise that a computer program should not be able to interpret the text displayed on the screen. You may have been asked to use CAPTCHAs before, when signing up for email accounts, social networks and some other online services.
