Math Spam Protection
Maintainers
- Will Rossiter (Nickname: willr, wrossiter)
Introduction
This module provides a simple math protection mechanism for prevent spam on your forms. It will ask the user to complete an equation such as "three plus seven".
Note that while the challenge is written in natural language to make it a bit harder to parse for bots, its by no means a comprehensive solution to avoiding spam.
Includes an EditableMathSpamField to integrate with the UserForms module.
Requirements
- SilverStripe 3.1
- Spam Protection
