Blacklist malicious fraud user in WooCommerce refers to any malicious activity where a user attempts to make an unauthorized or illegitimate purchase. This could include using stolen credit cards, chargeback fraud, or placing fake orders to exploit shipping and handling. Fraudulent activities not only affect your profits but can also damage your store’s reputation and lead to account bans or fines from payment processors. Implementing agile workflows in fraud detection processes could enhance the efficiency and security of your online store.
Understanding the Risks of Fraud in WooCommerce
Before we dive into the specifics of blacklisting fraudulent users, it’s important to understand the various risks that come with not dealing with fraud effectively:
- Financial Loss: The most obvious risk is financial loss due to chargebacks and refund requests from fraudulent transactions.
- Reputation Damage: A store that regularly experiences fraud may develop a reputation for poor security, deterring genuine users.
- Increased Operational Costs: Time spent investigating and handling fraudulent transactions, disputes with payment gateways, and chargebacks can add up quickly.
- Legal Liabilities: If fraud goes unnoticed or unaddressed, it may lead to legal issues or fines, particularly if payment processor policies are violated.
By implementing robust fraud detection and prevention strategies, you can minimize these risks and ensure that only legitimate users can purchase from your store.
How to Identify Fraudulent Users in WooCommerce
Before you can blacklist fraudulent users, you need to know how to identify them. There are several indicators of fraudulent behavior in WooCommerce:
1. Suspicious Payment Methods
Fraudsters often use stolen or fake payment methods. Look for:
- High transaction amounts: Unusually large orders can be a red flag.
- Unverifiable billing details: When the billing address doesn’t match the shipping address or cardholder name, it may indicate fraud.
- Multiple failed payment attempts: Several failed payment attempts can signal that a fraudster is testing a stolen card.
2. Frequent Order Changes
Malicious users may change their order details after purchase. If you notice that a user is altering their order information repeatedly, especially in a short time frame, it might be a sign of fraud.
3. Suspicious IP Address and Location
Fraudulent users often use VPNs to mask their actual location. However, you can still spot suspicious activity:
- Unusual IP addresses: Orders from countries or locations where you typically don’t have users can be a warning sign.
- Multiple orders from the same IP address: If several users are placing orders from the same IP address, especially in a short time, it could indicate fraud.
4. High-Risk Countries
Certain countries are known to be high-risk for fraudulent transactions. If your WooCommerce store ships internationally, monitor orders from countries that have a high rate of fraudulent activity. You can create custom rules to flag or block orders from specific regions.
5. User Behavior and Account Details
Fraudulent users often have inconsistent or incomplete account information. If an account profile seems rushed or lacks necessary details, it could be a sign of fraud.

Step 2: Set Up Blocking Rules in Aelia Blacklister
Once you’ve installed and activated the Aelia Blacklister plugin, it’s time to configure the rules to prevent fraudulent activities.
1. Block by Name and Surname
How to Block:

In the settings, you’ll find an option to block customers by their full names. Simply input the names (or surnames) of individuals you want to blacklist. You can block specific first names, last names, or combinations.
Why It’s Important:
Some fraudsters may change their contact details (email, phone number, IP) but continue to use the same name. Blocking names ensures they can’t complete transactions, even if other details are modified.
Steps to Block:
- Go to the “Blacklist Customer ” section in the plugin settings.
- Input the full name that you wish to block.
- Click Save or Update after adding the names.
2. Block by Address (Street, Postcode, City, Province/State, Country)
How to Block:

You can block entire addresses, including street, postcode, city, province, and country. This can help identify suspicious patterns, such as fraudsters using specific fake addresses repeatedly.
Why It’s Important:
Fraudsters sometimes use fake or stolen addresses, especially in regions known for fraudulent activities. Blocking specific addresses helps prevent them from completing purchases using fake information.
Steps to Block:
- In the Address section, enter the full address or parts of it (e.g., postcode, city, etc.) to block.
- You can specify whether to block by street, postal code, or region.
- Click Save after adding the address details.
3. Block by Email Address
How to Block:

Email addresses are commonly used for fraudulent sign-ups and orders. You can block specific email addresses or even entire domains (e.g., *@fakedomain.com).
Why It’s Important:
Many fraudsters rely on disposable or temporary email services to create fake accounts. Blocking emails prevents them from creating new accounts to abuse your store’s offers.
Steps to Block:
- Under Email Address, input the email or domain you wish to block (e.g., *@disposablemail.com).
- You can block a single email or a full domain (e.g., *@example.com).
- Save the changes to apply the block.
4. Block by Phone Number
How to Block:

Aelia Blacklister lets you block specific phone numbers or even area codes. Fraudsters often use fake or stolen phone numbers to make fraudulent purchases, and blocking them ensures these numbers can’t complete transactions.
Why It’s Important:
Fraudulent transactions can involve stolen phone numbers. Blocking numbers associated with known fraudsters adds an extra layer of protection.
Steps to Block:
- In the Phone Number section, input the phone numbers or area codes you want to block.
- You can block individual numbers or entire area codes if you notice a pattern of fraudulent activity from specific regions.
- Click Save after adding the phone numbers.
5. Block by IP Address
How to Block:

This is one of the most effective ways to stop fraudulent users. You can block specific IP addresses or ranges. Scammers often use the same IP address for multiple fraudulent transactions, so blocking these IPs can prevent repeated abuse.
Why It’s Important:
By blocking an IP address, you can prevent fraudsters from accessing your store from the same network. You can also block entire ranges of IP addresses using wildcards for added protection.
Steps to Block:
- Go to the IP Address section in the settings.
- Input the specific IP addresses you wish to block, or use wildcards to block entire ranges.
- For more advanced protection, you can use regular expressions (regex) to block IP patterns.
- Click Save to activate the IP block.
Final Step: Save and Apply Changes

After entering the details for each blocking method, make sure to Save or Update the settings to ensure the changes are applied. It’s important to regularly monitor and update your blacklist to ensure it stays effective against new fraudulent attempts.
