GravityCaptcha

GravityCaptcha is an easy, encrypted alternative to the frustrating Google Captcha. It adds a random math problem or word question to the end of your form. When a user enters the answer, it is compared to the answer on our external database. A wrong answer will prevent them from preventing the form. If a captcha question is compromised by spam bots and an entry gets through, site owners can mark the entry as spam and that question will be removed or changed in our secure database.
