Done! The users of your Tip Jar will periodically be required to answer a simple question they will see on their screen. If they don’t give the correct answer, they will be automatically logged out.
Copy the following parameters at the end of the configuration notecard of the Tip Jar, if you need to deeply configure the Captcha plugin.
CAPTCHA_TIMER: Set a number between 10 and 50 to adjust the timer the user of the tip jar has to select the right answer when the captcha dialog appears. [Default value = 30]
#CAPTCHA_TIMER = 30
CHAT_CHECK: Write YES if you want to prevent the captcha check from being performed if the user of the Tip Jar talks in the local chat. Otherwise write no. [Default value = NO]
#CHAT_CHECK = NO
EASY_CAPTCHA: Write YES if you want to make the captcha test easier, with a standard lowercase font and less options to choose from. Otherwise write NO. [Default value = NO]
#EASY_CAPTCHA = NO
