Simple but effective Anti-Spam solution for Ninja Forms and WPForms
Block form submissions containing words from the WordPress internal Comment Blocklist
Easy Setup
Privacy by design
OpenSource: GPLv2+

Short story behind this plugin
In May 2020 a spam botnet continuously sent spam messages through WordPress contact forms powered by Ninja Forms, which was very frustrating to a lot of users and administrators. Something had to be done about this.
Not reinventing the wheel
This plugin makes use of the WordPress internal Comment Blocklist. Blocklist validation in webforms is an easy and effective way to combat spam and prevent the same patterns of junk emails from appearing in your inbox over and over again.
Customizable
You can (temporarily) define your blocklist in the dashboard and retain full control of acceptable form submissions. The error message can be modified in the Theme Customizer.
Privacy by design
No captchas. No data sharing with third-parties. No external APIs. No logs. Just native WordPress functions.
Compatibility
Currently the plugin is only compatible with Ninja Forms (see #1) and WPForms.
