How WordPress User Registration Spam Impacts Your Site

Looking at the default WordPress registration page and you’ll see there is no particular step to prevent spam.

Once you allow public registration, your users easily access your site via the registration page at https://yoursite.com/wp-login.php?action=register:

If you don’t have any action to guard off this page or your site from spam, obviously your hard-to-make WordPress site can be on the prying eye of spambots and hackers.

Normally, spambots tend to create fake accounts as they are just scripts trying to access your site via the registration URL. Fortunately, you can easily swipe them away by just using contact form spam plugins.

On the other hand, you can consider some options, WordPress user registration spam spread by hackers is a real bear and can leave worse damage to your site. Once they get user access to your site, they might:

  • Steal user information like email addresses, credit card, or bank account information
  • Build backlinks to their websites
  • Flood your sites with porn links, scams, and even malware
  • Store pirated movies, documents, or software if they have admin access.

And you know what, the impact of such registration spam can be more severe than you can imagine. As soon as users register on your site, all their data will be stored in the database. Tons of registration spams can bulk up your database, which will drag down your site performance.

What’s more, spammy content, including junk links posted by spammers can affect your site ranking on search engines. Regarding junk links, they can redirect users to shady sites selling illegal drugs, weeds, or adult-content sites, which may ruin your site’s reputation.

On top of that, as search engines and hosting providers discover that your site is hacked, they suspend the site, mark it as deceptive, and blacklist it respectively.

Last but not least, your site may suffer from a data breach. Attackers can steal the personal data of your users and sell them online illegally.

Obviously, WordPress user registration spam proves a thorny issue that you shouldn’t turn a blind eye to.  So what’s next?

If you just run a personal blog, enabling user registration somehow turns out to be unnecessary. In fact, if you want to allow only several people access to your site, creating accounts for them rather than letting them register comes as a better idea.

To completely disable user registration on WordPress, you need to

  1. Log into your WordPress dashboard, go to Settings > General.
  2. In the General Settings page, scroll down to the Membership option and uncheck the “Anyone Can Register” box. Make sure to save your changes.

#2 Set Up User Roles in WordPress

In case you own a membership site and leaving user registration enabled is a must, it’s highly recommended never granting fresh members access to your WordPress dashboard.

As long as they are not admins, super admins (in a multisite), and editors, they cannot approve spam comments, publish harmful content, or set malicious functions in motion.

The safest user role you can assign to your new users is the Subscriber role as it has limited permissions in WordPress. For instance, Subscriber finds no way to access the WordPress Dashboard.

To set up user roles, what you need to do is:

  1. Open up the WordPress dashboard and click Settings > General.
  2. Look for the New User Default Role option and choose “Subscriber” in the drop-down menu. Hit “Save Changes.”

Humans can easily confirm their authentication by doing simple maths. Spambots, meanwhile, are not even able to see images, not to mention solving reCaptcha.

#5 Turn on Email Activation

Email activation requires users to confirm their authentication and humanity via a link attached to the email address used for registration. Clicking on the link means you activate the user account.

In other words, fake email addresses equal no account activation. Since most WordPress user registration spam is created by bots, utilizing the email verification method helps to apply an additional security layer for your site.

So how to implement email activation on your site?

Many versatile WordPress form plugins give the green light to create custom registration forms with an email verification feature. However, it’s available in the premium version only. If you’re willing to dip into your pocket, some options you can consider including Gravity Forms and Formidable Forms with the User Registration add-ons.

Alternately, you can opt for some free user registration plugins with a built-in email confirmation feature like User Registration or Profile Builder.

#6 Use Geo-blocking to Reduce Spam User Registrations

Geo-blocking refers to limiting users from certain countries from accessing your website.

You can whitelist your own country and then block every other country from reaching your registration page. By doing that, both malicious and legitimate traffic from the country you restrict access will be blocked right away.

Some geolocation plugins lending you a helping hand are iQ Block Country, CloudGuard, etc.

However, keep in mind that this method may not work well in some cases. For example, if you run a global eCommerce store, completely blocking customers from a specific country may refrain your site from driving more traffic and revenue.

#7 Change WordPress Registration URL

Another workable solution for reducing WordPress user registration spam is changing the URL of your registration page.

As mentioned above, the default WordPress registration page is located at https://example.com/wp-login.php?action=register. Customizing this link will fool spambot programmed to look for the default URL.

Considering the registration page is a part of your login page, customizing the login URL will enable you to change the registration page.

  2. Scroll down to see the WPS Hide Login area
  3. Type the new uniquely custom URL.
  • Login URL field: input your new Login URL path.

#8 Require Admin Approval for New Users

Apart from spam account themselves, you also need to take into account spam activities from registered users. That‘s why administrator approval for new users comes in handy.

  4. In case you want to approve/deny/delete multiple users at once, just choose pending users and click on the defined actions in the Bulk Actions dropdown.
    use the Bulk Action feature for multiple admin approval

#9 Manually Block Spam IP Addresses

This method permits you to stop users with a specific IP address from posting spammy comments on your site. If your registration spam bulk is caused by the same IP addresses, you can fix this problem by restricting those IP addresses from accessing your site in the first place.

We’ll show you how to block spam IP addresses using WordPress itself and the .htaccess file.

  • Blocking IP addresses in WordPress
  1. In your WordPress admin dashboard, head over to Settings > Discussion and scroll down to the “Disallow Comment Keys” option.
  2. Copy and paste the IP addresses that you want to block to the text box. Make sure to save your changes.

WordPress will now block users with these IP addresses from leaving a comment on your website. Although they are still able to visit your website, they will see an error message when trying to submit a comment.

  • Blocking an IP Address Using .htaccess

Note: Since a small coding mistake in the .htaccess file can cause internal server errors, you need to back up your existing .htaccess file beforehand. In case anything goes wrong, you can use the backup file.

  1. Log into your WordPress hosting account
  2. Navigate to the cPanel and go to Files > File Manager
  3. In the File Manager, look for the .htaccess file presented in the public_html folder. Right-click on it and choose Edit
  4. Add the code snippet below to your .htaccess file and hit Save Changes

order allow, deny

deny from xx.xx.xx.xxx

allow from all

Don’t forget to change “xx.xx.xx.xxx” to the IP addresses you want to restrict access to.

#10 Install a Security Plugin

WordPress security plugins can track down spammy, malicious IP addresses, and turn on a firewall to detect spammy login attempts and prevent hackers.

When you install these plugins on your site, they check every visitor’s IP against its database. If any conditions are met, they will refuse access. That will stop the spammer from registering a user account.

Plus, you can also make use of WordPress security plugins to implement geolocation blocks, scan vulnerabilities, and defense against brute force attacks.
