A CAPTCHA is a popular type of challenge–response test used to determine whether the user is real or a spam robot.
reCAPTCHA is the leading CAPTCHA provider, having been at the forefront of bot mitigation for over a decade.. It is effective, can scale and is offered for free.
Formspark's free integration with reCAPTCHA takes seconds to set up.
