Why Should You Stop WordPress User Registration Spam? 

In simple words, spams are unsolicited commercial messages. They contain a lot of similar messages and comments about irrelevant content and can be quite annoying to deal with.

How to Stop WordPress User Registration Spam? 

Now that you know how harmful spam can be, let’s discuss how to stop spam user registration on a WordPress site. 

Method 1: Using the User Registration Plugin 

The most effective way to prevent spam is by using a registration plugin that has the capabilities to stop registration spam. Out of various registration plugins available, only a few plugins have features to stop spam in the registration form.  

One such plugin is User Registration developed by WPEverest. It’s a free plugin with all the essential features to stop spam from your website registration.  

User Registration

So, we’ll be using this plugin to show you some easy steps to prevent spam. There are five ways through which you can stop WordPress registration spam with the help of this plugin.  

But before that, you’ll need to install the plugin and create a user registration form. After that you can implement the methods mentioned below: 

i) Using Admin Approval and Email Confirmation  

One of the best ways to block or stop spam is using admin approval on User Registration.  

In most cases, we can know whether it’s a WordPress registration spam or not by looking at the email address. So, if the email address seems to be spam or a fake user, the admin can manually deny the particular user’s registration.  

To activate the admin approval feature, log in to your WordPress site and go to User Registration>>Settings.  

User Registration and Settings

You’ll be provided with the User login option in the General section. Simply select Admin approval after registration from the dropdown. Save the changes when you’re done. 

Admin Approval After Registration

You can make further changes in the Email section for your admin approval to function as you wish. 

Email Settings

The users who’ve submitted the registration form on your website will appear on the Users page. Here, you can approve or deny their registration according to their email address.   

You can also block WordPress registration spam by approving users only after email confirmation. When a new user registers on your website, you can send a confirmation link to the user’s email address. Users can then access their new account by confirming their registration. 

If it’s a fake email address, it won’t be possible to open the confirmation link as the link will never be delivered. The real user will click the confirmation link if it’s a real account.  

For this, go to the User Registration>>Settings of your Dashboard. Then, under the User login option in the General section, select Email confirmation to login

Email Confirmation to Login

You can make the necessary changes in the Email confirmation configuration through the Emails section. 

Now, when a user registers through your form, you’ll see their verified status in the User Registration dashboard. If the status is pending for too long, you can know it’s spam. 

Meanwhile, you can also choose Admin approval after email confirmation option from the same User login option. It allows for approval of the user by the admin only after they verify their registration from the email sent to them.

ii) Using Google ReCaptcha and hCaptcha 

One of the easiest and most common ways to block spam bots is using Google reCaptcha. It’s a system developed by Google to distinguish whether a user is a human or not. It uses many techniques to determine the user as a human.  

The most common method is to use the “I’m not a robot” checkbox. Another method is to select some images from a given set of 9 images. Google reCaptcha analyzes the user behavior while interacting with these CAPTCHAs and decides if the user is real or a bot. 

So, if the WordPress registration spam is created with the spambots, they will never be able to pass this obstacle. 

You also have an option of enabling hCaptcha, a  spam protection method from Intuition Machines Inc. It’s similar to reCaptcha but doesn’t sell data obtained to any third party, unlike reCaptcha.  

To enable CAPTCHA, go to the User Registration>>Settings on the dashboard. Then click on the Integration section and select the CAPTCHA type you want to enable in your form.  

Select Captcha Type

Now, enter the Site Key and Secret Key and save the changes.  

Site and Secret Keys

You can get the keys from the official website of reCaptcha under the v3 Admin Console tab. On the other hand, visit to generate the site and secret keys for using hCaptcha. 

Next, open your registration form from User Registration on your dashboard and go to Form Settings. On the right side of the form settings, scroll down and find Enable Captcha Support. Now, check the checkbox to Enable Captcha support and click on the Update form

iii) Using Honeypot Spam Protection 

Honeypot spam protection is another option in the User Registration plugin to stop WordPress spam registration.  

As the name suggests, the honeypot is a trap developed to lure bots to reveal their identity. Once they’re caught, the program prevents them from form submission. Hence, it prevents WordPress’s new user registration spam.  

For this, open the user registration form in your WordPress dashboard to enable this option. Now, click on Form Setting >> Extras. You’ll see the available option on the right side, so check the box for Activate Spam Protection By Honeypot.  

Activate Spam Protection By Honeypot

Once you complete the process, click on the Update form button.

iv) Using Whitelisted Domains Registration 

Whitelisted Domains is the option that allows you to mark domains as trusted and allows form submission. This means when you add domains such as as Whitelisted Domains, you’ll receive the form only if the user’s email has the same domain. If users from other domains try to submit the form, they won’t be able to do so.  

To add the allowed domains, go to User Registration >> Settings. Under the General Options, you’ll see Whitelisted Domains.  

Whitelisted Domains

Now, add the domains such as,, and others that you consider genuine. Make sure you don’t separate the domains with commas or spaces; just hit enter and add another domain. 

As you save the changes, users whose emails are from the whitelisted domains can register to your site, while others can’t. 

v) Replacing Default Registration Page with Custom Registration Page 

Since it’s easy to find the WordPress login URL, some registration spams are sent targeting the login page of your WordPress website. To prevent this, you can redirect the wp-login page directly to the registration page of your website.   

You can create a custom login page using the User Registration plugin and redirect users from the default login page to the new page.

The spammers who search for the WordPress default login page will be automatically redirected to the registration page. So, they can’t send spam to the admin directly. The registration page can also be spam proofed using any techniques mentioned above.
