Description
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.
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. Built-in checkout email verification and phone verification can also challenge risky customers before an order is accepted.
The plugin works with WooCommerce Classic Checkout, WooCommerce Checkout Blocks, Contact Form 7, Gravity Forms, and WPForms.

FAQ
-
Do I need to configure settings after installation?
-
Yes. Go to Blacklist Manager > Settings and enable checks for checkout, registration, comments, reviews, forms, or REST API orders.
-
What is the Suspects list for?
-
The Suspects list gives you a review step before fully blocking a customer. Use it when an identity looks risky but should not be rejected immediately.
-
Can Blacklist Manager stop checkout through PayPal, Stripe, or another payment gateway?
-
Yes. Blacklist Manager checks customer details during the WooCommerce checkout and order creation flow before the payment gateway becomes the final decision point. Test custom checkout flows on staging.
-
Can this plugin stop contact form spam?
-
Yes. Blacklist Manager supports Contact Form 7, Gravity Forms, and WPForms submissions.
-
Does Blacklist Manager slow down my site?
-
Blacklist checks run only when needed, such as checkout, registration, comment submission, form submission, or API order creation. The checks are designed to stay lightweight.
-
No. The free plugin includes blacklist management, checkout protection, form protection, verification, notices, and dashboard stats. Premium adds risk scoring, automation, payment intelligence, device identity, activity logs, multi-store sync, and advanced integrations.
-
Global Blacklist Decisions is a connected fraud-prevention service. Data exchange depends on the Global Blacklist connection and checks you enable. Review the Global Blacklist settings, plan details, and privacy terms before using it in production.

Changelog
2.2.8 (Jul 12, 2026)
- Improve: Prevented the device identity seed cookie from being set server-side on product pages to preserve product page cache behavior.
- Improve: Deferred checkout device identity payload generation until the final Classic checkout submit or Store API checkout POST to reduce repeated checkout refresh work.
- Improve: Debounced checkout email and phone verification scripts so field validation is not repeatedly triggered by normal checkout refreshes.
- Improve: Added short checkout-attempt caching for strict Global Blacklist checks using cart, WooCommerce session, customer contact, IP, and browser context to avoid recalculating risk on validation retries.
- Improve: Added stable integration hooks (
wc_blacklist_manager_order_suspected,wc_blacklist_manager_order_blocked,wc_blacklist_manager_order_blacklist_removed, andwc_blacklist_manager_order_suspect_detected) with structured payloads for customer intelligence and external audit integrations.
