Gravity Perks Blocklist Addon GPL Overview:
Many years ago, we created GP Blacklist. It was and remains a simple perk that allows you to validate your Gravity Forms submissions against a list of undesirable words, phrases or IP addresses. WordPress previously called this list the Comment Blacklist. WordPress has renamed this setting to “Disallowed Comment Keys”. We were eager to follow suit but “GP Disallowed Comment Keys” just didn’t have a great ring to it. We’ve decided to keep it simple.
