Tired of cleaning up form submissions packed with profanity, competitors, or spam? You don’t need another blunt anti-spam plugin, you need full control.
Clio Banned Words plugin lets you define the rules, block the noise, and keep Elementor forms focused on real customers. Here is how to download and use our free plugin to block unwanted words from Elementor forms.
The Challenge: Unwanted Form Submissions
If you’ve built websites with Elementor and its powerful forms, you’ve likely encountered the frustration of spam submissions, inappropriate content, or users submitting forms with language that doesn’t align with your community guidelines. While there are general spam protection solutions, they often lack the specificity to target exact words or phrases you want to block.
That’s why we developed Clio Banned Words – a simple, lightweight, focused WordPress plugin that gives you control over what words cannot appear in your Elementor Forms submissions.
