How to Stop WordPress Comment Spam

There are several methods that allow you to stop WordPress spam comments. Some of these methods target spambots and keep them out of your website, while others are focused on moderating your comment section.

Here’s how to stop WordPress spam comments:

1. Use Custom CAPTCHA to Prevent Comment Spam

The first method to avoid spam comments is preventing bots from leaving comments. For this, you can use a CAPTCHA, which is a form that requires users to solve a puzzle or identify a set of images to proceed further. These puzzles are easy for humans and difficult for bots to bypass.

Google reCAPTCHA is one of the most popular forms of CAPTCHA. Google offers many types of CAPTCHA.

  • reCAPTCHA v2 requires a user to solve a puzzle.
  • Invisible reCAPTCHA v2 and reCAPTCHA v3 monitors user activity in the background and assigns a score to decide if the user is a human.

An easy way to add Google reCAPTCHA to stop spam comments in WordPress is to use the Nexter Blocks. With this plugin you can set up reCAPTCHA in just a few steps and secure your website from malicious comments.

To start, visit the Google reCAPTCHA page and log in to your Google account.

Add a label, select the reCAPTCHA version you wish to use and provide your domain. Submit to proceed further.

You will then be provided with a site key and a secret key, which you need to save securely to activate your reCAPTCHA.

Save your site and security key

Now, proceed to your WordPress dashboard and navigate to Appearances> Nexter Settings> Extra Options. Here, you will find Google reCAPTCHA. Click Enable, and then click the gear icon to open the settings.

Click on gear icon

In the pop up, select the reCAPTCHA version, enter your site key and your secret key and select locations on your website where you want Google reCAPTCHA to function. Once you’ve entered all the details, click Save.

enter your site key and your secret key

Note: Before adding reCAPTCHA to your website, consider factors such as accessibility to disabled users and overall user experience. Make sure to select a Google reCAPTCHA version that protects your website without compromising on the experience that users have.

2. Disable Comments

If you get a lot of spam comments on your website and moderating them has become time-consuming, you might want to consider disabling comments altogether. You can choose to disable comments across your entire website or for specific posts and pages.

WordPress allows you to disable and enable comments manually. Navigate to Settings > Discussion and unselect the option to “Allow people to submit comments on new posts” and Save Changes.

This setting does not remove existing comments and can be overridden on future posts and pages.

Tick the Allow people to submit comments on new posts

WordPress also allows you to manually disable comments for individual posts and pages. Navigate to All Posts and Quick Edit the post for which you want to disable comments. Now head uncheck the Allow Comments and click Update option to disable comments for that post.

Quick Edit the post for which you want to disable comments

If you have a smaller website manually disabling comments through your WordPress discussion settings is feasible. However, this can be time-consuming if you have a lot of pages and posts up. In this case, you can use the Nexter Blocks plugin. This plugin comes with 90+ Gutenberg blocks and expands the functionality of your website.

After installing the Nexter Blocks plugin, navigate to Appearance > Nexter Settings > Performance. Select Disable Comments> Settings.

Use Disable Comments by

In the dialogue box, from the Comments dropdown, choose Disable Everywhere. This disables comments across your website and can’t be overridden on pages or posts.

Choose Disable Everywhere

You can also use the Nexter Blocks settings to disable comments for specific post types. In the Disable Comments dialog box, select “Disable Specific Post Type”. This will show you 4 options below:

select Disable Specific Post Type

Select the post types that are applicable and Save.

Disabling comments removes any potential for spam but also halts all user engagement through comments. A perfect middle ground would be to disable comments on post types that receive a larger volume of spam comments while keeping other sections open for comments.

3. Require User Registration

If you do not want to disable your comment section entirely, you can avoid spam comments on WordPress to a certain extent by requiring your users to register before they comment. To do this, navigate to Settings>Discussion from your WordPress dashboard and select “Users must be registered and logged in to comment” under Other Comment Settings.

select Users must be registered and logged in to comment

To make the commenting experience smoother for legitimate human users, you can use the Comment Form from Nexter Blocks. These forms provide a column for Name and Email Address, allowing users to register before they comment. Combine this with the option to add Google reCAPTCHA through Nexter Settings, and you have a formidable barrier against WordPress comment spam.

If your site receives a high volume of comments, requiring user registration adds an extra layer of security. It makes it harder for spammers to post multiple comments.

4. Limit or Ban Links in Comments

Most malicious spam bots leave unwanted comments with phishing links or spam links that redirect your traffic to other websites. Often, limiting users’ ability to comment with links solves the spam comment issue.

From your WordPress Dashboard, head to Settings > Discussion > Comment Moderation. Here, you can set the number of links a comment can have. If you want to allow links but limit their number, select add the number here. If you want to prevent bot spam links in your comments altogether, set it to Zero, and WordPress will block all comments that contain links.

Enable Comment Moderation

With this setting, if a comment contains a link it will be redirected to the moderation queue from where you can manually decide whether it should be displayed or not.

5. Enable Comment Moderation

Comment Moderation is a manual option to block spam comments on WordPress. This feature allows you to view and verify comments before they actually appear on your website for viewers to see. Comment Moderation gives you control over what type of comments are posted on your website and lets you filter out spam comments.

To enable comment moderation, navigate to Settings>Discussion. In the Before a comment appears section, select the parameters based on how you would like to manage comments.

Enable Comment Moderation 1

Check Comment must be manually approved if you wish to moderate all comments.

If you wish to moderate comments only by new users, you can select Comment author must have a previously approved comment. This way, all comments made by unapproved users will be held back for moderation.

To make the moderation process easier, under the Email me whenever section, check the boxes for Anyone posts a comment and A comment is held for moderation.

Save the changes.

Note: While moderation enhances spam protection gives you control over what is published on your website, it requires a serious time commitment, especially if you have a larger website. If you don’t have the time to review comments regularly, they could pile up, delaying interaction with genuine users.
