Chargify has made a change to the settings for Public Signup Pages (PSP) for increased security and reduced risk of fraud. CAPTCHA is now set by default for all newly enabled PSPs. This change does not apply to previously created sign up pages. CAPTCHA is used to prevent automated bots from conducting fraudulent activity by authenticating that the site user is a person. Enabling CAPTCHA on your sign-up pages creates a more secure experience for your customers.
