Every once in a while, a website will ask you to select all of the images that correspond with the clue in order to submit a contact form or sign up for an account. These are called CAPTCHAs (which stands for "Completely Automated Public Turing test to tell Computers and Humans Apart"), and their purpose is to verify that you're a real human. Spammers sometimes write computer programs that automatically fill out forms, so using CAPTCHAs can help to reduce spam. The CAPTCHA we use at eLYK Innovation is called reCAPTCHA, which includes an audio CAPTCHA for the visually impaired. So, the next time a web page asks you to solve the clue remember that it's for your own good.
