Gravity Perks Comment Blacklist is a WordPress plugin that allows you to validate Gravity Forms field values against the native WordPress Disallowed Comment Keys validation. The plugin prevents form submissions that include blocked phrases, specific words, or blacklisted IP addresses. This provides a direct bridge between your site-wide discussion settings and your lead generation forms.
WPExclusive members get access to Comment Blacklist as part of a full plugin and theme library — plans from $9.99/month. See the full Gravity Perks collection →
What Is Gravity Perks Comment Blacklist?
Gravity Perks Comment Blacklist is developed by Gravity Wiz and is a forms extension plugin for WordPress. It belongs to the forms category on WPExclusive, alongside other tools for advanced data collection. Recently rebranded as GP Blocklist, it ensures your forms remain free from junk data without requiring third-party API keys for basic filtering.
The plugin solves the problem of automated spam and unwanted keywords by leveraging the built-in WordPress blocklist managed in your discussion settings. It is designed for site owners who need granular control over what specific terms are permitted in form entries.
Gravity Perks Comment Blacklist Features
The feature set is built around synchronizing WordPress core moderation tools with Gravity Forms validation logic.
Flexible Validation Scopes
Comment Blacklist allows for versatile implementation depending on your form requirements. You can apply validation to a single specific field, multiple selected fields, or enforce the blocklist across all fields within a form. This is particularly useful for protecting sensitive inputs like subject lines or message bodies while leaving other fields unrestricted. Detailed configuration is managed directly within the Gravity Perks Perk settings tab.
Advanced Blocking Logic
The plugin supports more than just simple keywords. You can specify single IP addresses or entire IP ranges within the WordPress Disallowed Comment Keys to prevent submissions from known malicious sources. It also includes a honeypot feature that can be used via hooks to reject submissions silently. This makes it appear successful to the spammer while ensuring no entry is actually created in your database.
WordPress Core Integration
Rather than requiring a separate interface for managing blocked words, the plugin uses the existing WordPress Discussion settings (Settings > Discussion). Any phrase entered in the Disallowed Comment Keys section will automatically trigger validation errors in your forms. This centralized management simplifies administration for users who already moderate a busy blog section.

Use Cases
Preventing Spam and Bot Submissions
By blocking known spam phrases such as “viagra” or “crypto lottery,” you can significantly reduce the volume of junk in your inbox. This is a vital part of security for public-facing contact forms.
Reserved Usernames and Brand Protection
If you use Gravity Forms for user registration, you can prevent users from registering names like “Admin” or “Staff” by adding them to the blocklist. This protects your brand identity and prevents administrative impersonation.
Invalid Promo Code Prevention
You can quickly block leaked or unauthorized promo codes from being used in a form by simply adding them to your WordPress discussion blocklist. This provides an immediate stopgap without needing to modify form logic.
Agencies and Developers Managing Multiple Client Sites
Agencies can deploy standardized blocklists across all client websites by using this plugin in combination with a membership from WPExclusive. This ensures a consistent baseline of protection without incurring separate license costs for every domain.
