How to Block Fraud Users in WooCommerce and Protect Your Online Store
Blocking fraudulent users is not simply a precaution; it is an essential step to safeguard your business from financial losses and ensure a secure shopping experience for genuine customers. By proactively identifying and restricting fraudulent users, you can maintain trust, reduce risk, and focus on growing your store.
One powerful solution designed specifically for WooCommerce is Aelia Blacklister for WooCommerce. This plugin helps you block unwanted users by leveraging IP addresses, email domains, and other identifiers, enabling you to protect your store effectively and efficiently. In this article, we’ll explore the threats posed by fraud in WooCommerce, why manual detection often falls short, and exactly how to use Aelia Blacklister to safeguard your online store from fraudsters.
1. Understanding Fraud in WooCommerce

Fraud is a growing concern for online store owners, especially those using WooCommerce, one of the world’s leading eCommerce platforms. To effectively protect your store, it’s vital to understand the most common types of fraud affecting WooCommerce businesses.
Common Types of Fraud in WooCommerce Stores
Credit Card Fraud: Perhaps the most prevalent form, this involves stolen credit card information being used to make unauthorised purchases. Fraudsters often use automated bots or manually attempt to test stolen cards at your store.
Fake Accounts: Fraudsters create fake user accounts to exploit promotions, abuse referral systems, or launder stolen goods. These accounts can bypass basic verification, making it difficult to detect without advanced tools. To further reduce spam and fraudulent sign-ups, consider implementing email blacklisting techniques — learn more about this in our detailed guide on email blacklisting in WooCommerce.
Chargebacks and Friendly Fraud: In chargeback fraud, customers dispute legitimate transactions with their banks, claiming they never received goods or services. This leads to financial losses and additional administrative burdens.
Bot Attacks and Credential Stuffing: Automated bots attempt to log in using stolen credentials or scrape pricing and inventory data. This can cause slow site performance and expose your store to security vulnerabilities.
Proxy and VPN Abuse: Fraudsters often use proxy servers or VPNs to hide their real IP addresses, making it difficult to track and block malicious users.
Fraudulent activity doesn’t just result in immediate financial losses — it can also severely impact your business reputation and customer trust. Chargebacks and fraudulent orders increase operational costs and can lead to higher payment processing fees. Moreover, if customers feel your store is insecure or frequently victim to fraud, they are less likely to return, harming your long-term growth.
2. Why Blocking Fraudulent Users is an Effective Strategy
Proactive prevention is essential to reducing the damage caused by fraudulent users in your WooCommerce store. Rather than reacting after a fraudulent order has been placed—when financial loss and reputational damage have already occurred—blocking suspicious users upfront helps minimise risks and protect your business more effectively.
The Importance of Proactive Fraud Prevention
By identifying and blocking users before they complete transactions, you:
Avoid Costly Chargebacks: Fraudulent orders often result in chargebacks, which can be expensive due to lost sales, bank fees, and penalties. Early blocking stops these before they happen.
Reduce Manual Order Reviews: Automating fraud prevention through user blocking decreases the time your team spends scrutinising orders, allowing staff to focus on fulfilling legitimate sales and improving customer experience.
Maintain a Smoother Checkout Experience: Genuine customers benefit from faster, frictionless transactions without delays caused by additional fraud checks.
Protect Your Store’s Reputation: Customers trust stores that handle payments securely and avoid fraud-related issues. Preventing fraud upfront enhances your brand credibility and customer loyalty.
Lower Operational Costs: Fraud prevention reduces the costs linked to refunds, shipping products to fraudsters, and customer support related to disputes.
Limitations of Default WooCommerce Features Regarding Fraud Blocking
While WooCommerce provides basic security functions, it lacks comprehensive tools to block fraudulent users effectively:
No IP or Email Blocking: WooCommerce doesn’t natively offer the ability to block users by IP address, email domain, phone number, or other identifiers commonly used in fraud detection.
Limited Fraud Detection: It cannot detect sophisticated tactics such as VPN use, proxy masking, or device fingerprinting, which fraudsters often use to hide their identity.
No Advanced Filtering or Automation: WooCommerce’s default features do not support advanced matching rules like partial or pattern-based matching using regular expressions.
Because of these limitations, relying solely on WooCommerce leaves your store vulnerable to evolving and complex fraud attempts.

3. Introducing Aelia Blacklister for WooCommerce
Protecting your WooCommerce store from fraudulent orders requires powerful, flexible tools, and Aelia Blacklister is a standout solution designed specifically for this purpose. With an impressive rating of 4.67 out of 5 from users, this plugin empowers WooCommerce store owners to refuse orders from suspicious visitors based on customisable filtering rules.
Overview of the Plugin and Its Purpose
Aelia Blacklister lets you block orders based on a wide range of customer information, including:
Customer’s name and surname
Address details such as street, postcode, city, state/province, and country
Email address
Phone number
IP address
The plugin supports both exact matches and partial matches using regular expressions (for all fields except IP addresses). For IP addresses, you can block specific IPs, IP address ranges, or use IP masks for more advanced filtering. This granular control allows you to stop fraudulent users at the checkout stage before they can place an order.
When a blocked visitor attempts to complete a purchase, the checkout is halted, and a customisable error message appears to inform them why the order cannot be processed. This seamless integration with WooCommerce ensures a smooth experience for legitimate customers while effectively preventing fraud.
Key Benefits for WooCommerce Store Owners
Comprehensive Blocking Options: Blacklist users by name, address, email, phone number, and IP address with high precision.
Flexible Matching Rules: Use exact matches or powerful regular expressions to cover complex fraud patterns.
Customisable Customer Messages: Tailor the error messages shown to blocked users for better communication.
Easy Management: The plugin adds a dedicated menu in the WooCommerce backend to configure and manage blacklist rules effortlessly.
Improved Fraud Prevention: By stopping fraudulent orders before they happen, you reduce chargebacks and save time on manual reviews.

1. Block by Name and Surname
How to Block:

Navigate to the blacklist settings and enter full names or surnames to block. You can specify first names, last names, or both.
Why It Matters:
Fraudsters may change contact details like email or IP, but often reuse the same names. Blocking by name helps prevent them from bypassing your security.
Steps:
Open the Blacklist Customer section.
Add the names to be blocked.
Save the settings.
2. Block by Address (Street, Postcode, City, Province/State, Country)
How to Block:

Block specific address components such as street, postal code, city, region, or country.
Why It Matters:
Fraudsters commonly use fake or stolen addresses, often from high-risk locations. Blocking these helps prevent fraudulent purchases.
Steps:
Enter full or partial address details.
Specify the level of detail for blocking.
Save your changes.
3. Block by Email Address

How to Block:
Add specific email addresses or entire domains, including disposable email providers, using wildcards (e.g., *@tempmail.com).
Why It Matters:
Many fraudsters use temporary or throwaway email accounts. Blocking these prevents them from abusing your store.
Steps:
Add emails or domains to the Email Address field.
Save the settings.
4. Block by Phone Number
How to Block:

Input individual phone numbers or entire area codes to block.
Why It Matters:
Fraudsters often use fake or stolen phone numbers. Blocking suspicious numbers adds an extra layer of security.

Add phone numbers or area codes.
Save the updates.
5. Block by IP Address
How to Block:

Block single IP addresses or entire ranges using wildcards or regular expressions for patterns of abusive behaviour.
Why It Matters:
Blocking IP addresses prevents fraudsters from repeatedly accessing your store from the same networks.
Steps:
Access the IP Address settings.
Enter specific IPs or use wildcards for ranges.
For advanced blocking, use regex patterns.
Save the configuration.
Final Step: Save and Activate Your Rules
After entering your blocking criteria, make sure to save or update your settings to activate the blacklist rules. It’s important to regularly review and update your blacklist to stay ahead of new fraud attempts and keep your WooCommerce store secure.
