Comment Blacklist Manager vs Blacklist Manager – WooCommerce Anti-Fraud, Blacklist & Checkout Verification

Comment Blacklist Manager retrieves a list of terms from a remote source and updates the disallowed_keys setting in WordPress. The plugin will automatically fetch a list of terms on a regular schedule and update the contents of the “Disallowed Comment Keys” field. Terms added manually via the “Local Blacklist” field will be retained during the scheduled updates. Terms added manually to the “Excluded Terms” field will be removed from the list. The default list of terms is fetched from a GitHub repository maintained by Grant Hutchinson.

Blacklist Manager is a WooCommerce blacklist, anti-fraud, and spam prevention plugin for stores that need to block fake orders, suspicious customers, spam registrations, and unwanted form submissions. The free plugin is a complete local protection toolkit, not a Premium trial. Use blacklist rules for phone numbers, email addresses, IP addresses, and email domains at WooCommerce checkout, registration, comments, product reviews, REST API orders, and supported WordPress forms. The plugin works with WooCommerce Classic Checkout, WooCommerce Checkout Blocks, Contact Form 7, Gravity Forms, and WPForms. What the free plugin includes Manage local email, phone, IP address, and email-domain entries through Suspects and Blocklist workflows. Stop matching identities at WooCommerce checkout and protect registration, comments, product reviews, supported forms, and WooCommerce REST API orders. Require built-in checkout email verification for the policies you configure. Core owns and runs email verification; phone OTP and Twilio/TextMagic SMS transport belong to Blacklist Manager Premium. Configure free customer notices and admin alerts, then review dashboard blacklist and detection statistics.

It is not required for local Core protection and is not a prerequisite for Premium.
