Captcha

CAPTCHA is a pop-up to identify whether or not a user is a robot, where 5 characters appear to be typed to continue creating a account. These characters can appear in upper or lowercase, randomly. This function was added to prevent more Pous from being banned for using cheats, in version 1.4.96. This appears right after the player confirms the Pou account email. 
CAPTCHA is also made up of a series of lines and dots, which serve to make it difficult for any supposed robot to read. Its impossible to create some Pou account without CAPTCHA success.
== Trivia ==
* Regardless of whether the characters appear in lowercase or uppercase, the CAPTCHA is accepted even if you type everything in one way.
* Since some letters can be confused with numbers, there are some characters that can be replaced:
** The letter 'g' can be replaced by the number '9';
** The letter 's' can be replaced by the number '5';
** The letter 'o' can be replaced by the number '0'.
