When someone visits a website, they typically have a goal in mind, and a certain expectation that they plan to achieve. User tolerance isn’t infinite however: aggrevate a viewer too much, and they will give up their goals eventually.
Strangely enough, we’ve invented a standard that’s been proven to do just that. CAPTCHA (or Completely Automated Public Turing test to Tell Computers and Humans Apart) is a method that we employ on websites to verify that a user is a human instead of, say, spam bots or some other malicious software pretending to be human. CAPTCHA’s are frequently used in user registrations, comment submission forms, and many other interactive online interfaces.
