If you’ve ever logged into your WordPress dashboard to find your comments section overflowing with irrelevant messages, you’re not alone. In 2025, unprotected WordPress sites are seeing anywhere from 50 to over 500 spam comments a day, according to JACKOBE, and that’s before you even count contact form spam.

In this post, I’ll break down ways to track and managing spam comments on WordPress websites. And essential ways for maintaining a clean, functional, and user-friendly site and avoid spam which can clutter your website's database, degrade user experience, and even harm your site's SEO.

Here’s how you can effectively track and manage spam on your WordPress website:
1. Install a WordPress Spam Protection Plugin
Using a dedicated plugin is one of the easiest and most effective ways to track and control spam. Some of the most popular spam protection plugins include:
- Akismet Anti-Spam: Akismet is one of the most widely used anti-spam plugins for WordPress. It automatically checks comments and contact form submissions against its global database of spam and flags suspicious entries. It works in the background, making it easy to track and block spam on WordPress without much effort.
- Antispam Bee: This WordPress plugin helps block spam comments and trackbacks while allowing you to control which comments are automatically marked as spam. It offers various filtering options based on IP addresses, time between posts, and more.
- WP SpamShield: This WordPress plugin provides advanced spam blocking for comments, registration, and contact forms. It can automatically detect and block spambots and other forms of spam.
2. Monitor and Moderate Comments Regularly
Even with WordPress spam protection plugins, it's still a good idea to regularly moderate comments on your WordPress site. This allows you to catch any WordPress spam that might slip through the cracks. You can monitor comments by:
- Enabling comment moderation in the Discussion Settings of your WordPress dashboard. This way, comments are held for approval before being publicly visible.
- Setting up a threshold for comment approval. For example, comments from users with links or more than a certain number of words can be marked as potential spam on your WordPress blog.
- Reviewing the Spam Folder in the WordPress comment section (under Comments > Spam) and cleaning it up regularly.
3. Use CAPTCHA or reCAPTCHA
Another effective way to prevent spam submissions on forms (like contact forms or registration forms) is by adding a CAPTCHA or Google reCAPTCHA. This forces users to verify they are human before submitting any form. Plugins like Google Captcha (reCAPTCHA) or WPForms offer easy integrations for this.
- Google reCAPTCHA: Helps prevent bot spam on your WordPress forms by adding a simple checkbox or invisible challenge to verify users.
- WPForms: This plugin integrates with Google reCAPTCHA and other CAPTCHA services to ensure WordPress spam bots can't easily submit form entries.
4. Block Spam IP Addresses and User Agents
If you notice a particular pattern of spam originating from specific IP addresses or user agents, you can block spam traffic on WordPress manually. WordPress plugins like Wordfence Security or iThemes Security allow you to block suspicious IPs and user agents.
- In Wordfence, go to Wordfence > Firewall > Blocking to manually add IPs or use the Live Traffic feature to monitor suspicious activity in real-time.
- iThemes Security has features for blocking malicious login attempts or suspicious IP addresses associated with spam or hacking attempts.
5. Enable Comment Blacklist
WordPress has a built-in blacklist feature that allows you to automatically mark specific words, links, or IP addresses as spam. To enable this, go to Settings > Discussion, and under the Comment Blacklist section, add common spammy words or phrases (such as "buy cheap drugs", etc.) that often appear in spam comments.
Any comment containing these words or links will be automatically flagged as spam.
6. Review Contact Form Submissions for Spam
Contact forms are often targeted for spam, so ensure you are reviewing all form submissions for suspicious activity. Some form plugins (like Contact Form 7 and WPForms) include built-in spam protection mechanisms like reCAPTCHA, but it’s important to regularly check submissions for potential spam.
- Contact Form 7: You can enable reCAPTCHA and Akismet integration to track and prevent spam submissions.
- WPForms: Integrates seamlessly with reCAPTCHA and includes built-in anti-spam features to protect your forms from bot submissions.
7. Use a Honeypot Technique
A honeypot technique involves adding hidden fields to forms that are invisible to humans but visible to bots. When a bot fills in the hidden field, it’s immediately flagged as spam. Some plugins, like Antispam Bee, and WPForms, offer built-in honeypot functionality.
8. Regularly Clean Up Your WordPress Database
Over time, spam comments, registrations, and form submissions can accumulate in your WordPress database, slowing down your website. Regularly cleaning your database of unnecessary spam data can improve WordPress site performance. Plugins like WP-Optimize or Advanced Database Cleaner can help you easily remove old spam comments and database clutter.
