An example of captcha when you are registering your account
A
CAPTCHA (an acronym for "
Completely
Automated
Public
Turing test to tell
Computers and
Humans
Apart") is a type of challenge-response test used in computing to determine whether or not the user is human. This form of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen. Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a CAPTCHA is sometimes described as a reverse Turing test.
The Captcha can occur when you train (usually before the super soldier medal), work (usually before the hard worker medal), send messages, support resistance wars, subscribe newspapers and vote.
Becoming a part of the Loyalty program disables captcha for working, training, sending messages and voting. However, all players still see captcha for every fifth newspaper they subscribe.
