Gravity Forms Blocklist
Validate a field’s value against the WordPress Disallowed Comment Keys validation.
What does it do?
This plugin allows you to validate a field’s value against the WordPress Disallowed Comment Keys validation. This option can be set for a single field, multiple fields, all fields within a form. If the field fails validation it will display an error to the end user stating that their field contains disallowed words.

How do I enable this functionality?
Since there are two options for this perk, field and form, we will do them in separate categories.
To activate blocklist validation for a single field, navigate to the Perks tab and check Validate Against Disallowed Comment Keys.
To validate against every field on the form, navigate to the “Restrictions” section within the form settings area. Check Validate Against the WordPress Disallowed Comment Keys.
If a single field has the Blocklist setting enabled then that field will take the end-users submitted value and check it against that of the Disallowed Comment Keys words.
If the form wide Blocklist setting is enabled then it loops through all fields within the form when an end-user submits the form. It then checks the fields to see if they are supported by this perk. After grabbing a list of all supported fields it then validates the fields against the WordPress Disallowed Comment Keys words.
WordPress Disallowed Comment Keys
To specify blocked words, navigate to Settings > Discussion. Scroll down to “Disallowed Comment Keys” and enter any words you wish to prevent from being submitted on this form, one per line.
You can specify IP addresses in the Comment Keys and GF Blocklist will prevent submissions from that IP.
Automate Blocklist Management
Save yourself time and beef up your blocklist by supplementing the list of keywords with this repository. You can add the list to your site by pasting it into the Disallowed Comment Keys, or you can use any of the supported plugins that automates adding new keywords.
Use the gpb_enable_honeypot hook to silently reject submissions while making it appear successful. This discourages spammers from attempting to find loopholes in your blocklist to exploit.
Due to the nature of WordPress’ Disallowed Comment Keys feature, it will match words inside of other words. So let’s say you wanted to ban the word Race it would also ban any words with race in it, like Racer.
This Perk was previously known as GF Comment Blacklist. We chose to rename it to match name changes in WordPress.
How can I change the text of the validation error message?
You can change the text of the validation error by using the gpb_validation_message hook.
