You can add a confirmation “I'm not a robot” (CAPTCHA) in any of your registration or order forms. This feature will reduce the number of spam registrations. However, it will inevitably reduce conversion, so we don't recommend using it unnecessarily.
An order that was created accidentally or for a test purpose can be transferred to the “False” status. This status essentially means deleting an order. This kind of order will not appear in the general list of orders and taken into account in sales statistics.
It often happens when users fill in a form on a website, get to a purchase page, but leave it without making a purchase. As a result an unpaid order appears in the system.
With rising of number of users a number of unpaid orders is increasing too. It is possible to deal with them in GetCourse.
