Are spam comments swamping your WordPress site? Sick of sifting through offers for designer handbags, pharmaceuticals, and random link dropping in your posts‘ discussions?
You‘re far from alone. As the powering over of all websites, WordPress is a prime target for comment spammers. A staggering 84% of all comments made online are spam, according to recent research from Statista.
But don‘t wave the white flag just yet! With the right combination of WordPress settings, plugins, and proactive moderation, you can stop spammers in their tracks and keep your comment section a safe space for genuine conversation.
In this ultimate guide, we‘ll equip you with 15+ battle-tested tips and tools to conquer the comment spam siege in 2023. By the end, you‘ll have an impenetrable defense against the bots and a thriving community of engaged readers. Let‘s dive in!
Why Is Comment Spam Such a Scourge?
First, let‘s quantify the enemy. Parsing through a few junky comments may seem like a minor annoyance. But at scale, comment spam can wreak havoc on your WordPress site in insidious ways:
Ruins your reputation – A comment section clogged with irrelevant offers and links makes your site look neglected, unprofessional, and untrustworthy to visitors.
Drives away engagement – When spam comments drown out real discussion, readers are less likely to participate. You lose out on valuable feedback, questions, and community-building.
Devours your time – Comment moderation is tedious enough. But when you‘re battling an onslaught of spam submissions, it can quickly eat up hours of your workweek better spent creating content.
Jeopardizes your SEO – While most comment links are "nofollow", some shady SEO plugins override this. Unsavory links in your comments can harm your search rankings and get your site penalized.
Spreads malware to visitors – Particularly malicious comment spam can attempt to infect your readers‘ devices with viruses, trojans, and other software nasties when they click the links.
Still not convinced of the spam epidemic‘s urgency? Chew on these eye-popping stats:
| Fact | Figure |
|---|---|
| Percentage of comments that are spam | 84% |
| Number of spam comments left each day | 1.5M/hour |
| Percentage of all Internet traffic attributed to spam | 28% |
| Economic cost of spam per year | $20B in lost productivity |

Common Types of Comment Spam
Comment spam comes in many nefarious flavors. Familiarizing yourself with the most pervasive forms can help you spot and crucify it swiftly:
Link building spam – The most common culprit. Stuffing comments with links in a misguided attempt to juice search rankings. Usually accompanied by generic compliments like "great post!"
Ads/affiliate spam – Hawking questionable products and services (pills, handbags, adult entertainment). Often from suspicious URLs jam-packed with hyphens and numbers.
Phishing/malware spam – Comments with links that direct to malicious sites containing drive-by downloads, malware droppers, and credential-harvesting pages.
Nonsensical spam – Random text snippets, word salad, or whole paragraphs lifted from the post itself in an attempt to slip past rudimentary spam filters.
Trolling/harassment – Inflammatory remarks, personal attacks, profanity, hate speech, and other guideline-breaking garbage intended to get a rise out of you or your readers.
Step 1: Configure Your WordPress Discussion Settings
Your first line of defense against the comment spam horde is battening down the hatches on your WordPress discussion settings. Here‘s how:
- From your WordPress dashboard, navigate to Settings > Discussion
- Under "Comment Moderation", tick the following:
- [X] Comment must be manually approved
- [X] Comment author must have a previously approved comment
- Under "Comment Blocklist", add any spammy keywords, URLs, names, and IPs you want to block
- Under "Avatars", set the default avatar to "Blank" to discourage spam bots
- Under "Other Comment Settings":
- [X] Users must be registered and logged in to comment
- [X] Automatically close comments on posts older than X days (where X is your preference)
- Save changes
With these settings locked in, you‘ve effectively blocked drive-by comment spam, empowered yourself to pre-screen new commenters, and closed the window on old posts that attract spam.
Step 2: Deploy Anti-Spam Plugins
Now that you‘ve shored up WordPress‘ built-in anti-spam controls, it‘s time to bring out the big guns: plugins purpose-built to crush comment spam. Here are our top picks for 2023:

For the tech-savvy, there are a few advanced anti-spam tactics worth exploring:
1. .htaccess Blocking
By editing your site‘s .htaccess file, you can block spammy IP addresses, user agents, and referring domains at the server level before they even load WordPress.
For example, adding this directive will block an IP address:
Require not ip 123.456.78.92. Rename wp-comments-post.php
Many comment spam bots target wp-comments-post.php. By renaming this file to something obscure, you can thwart these automated attacks.
Just be sure to also modify the comment form code in your theme to reference the new name.
3. Honeypot Fields
Like bear traps for bots! The idea is simple:
- Add an empty form field (e.g. url2) to your comment form
- Hide it with CSS (display: none;) so humans can‘t see it
- Legitimate readers will leave it blank
- Spam bots will fill it out
- Server-side script checks if url2 is filled out
- If so, reject the comment
Most savvy WordPress anti-spam plugins have honeypot functionality baked in. But if you want to roll your own, here‘s a handy guide from Smashing Magazine.
Step 4: Foster Authentic Engagement
The best defense against comment spam is a thriving community of real readers who consistently post thoughtful, relevant remarks. But how do you get there?
1. Be an active host
Don‘t just use your comment section as a link farm. Dive into the discussion! When readers leave articulate comments, recognize them with a response. Make your commenters feel heard and appreciated.
2. Highlight the best comments
Have a "Comment of the Week" feature where you showcase an all-star remark. Create a monthly roundup post linking to your most lively comment threads. By rewarding quality participation, you incentivize more of it.
3. Ask compelling questions
Explicitly invite readers to weigh in by closing your posts with open-ended discussion prompts. What did they find most helpful in the article? How have they dealt with the problem you‘re addressing? The more specific, the better.
The Nuclear Option: Disable Comments
If you‘ve exhausted all spam-fighting options and the flood persists, you may need to resort to the nuclear option: disabling WordPress comments entirely.
From Settings > Discussion, uncheck "Allow people to post comments on new articles".
You can also disable comments on a per-post basis via the Discussion metabox.
Yes, this is an extreme measure that cuts off engagement. But if moderating spam comments is eating up time better spent creating content, it may be necessary. You can always direct readers to interact on social media or your email list instead.
Stay Vigilant Against Spam
Spam is the price of success in the WordPress world. As your site‘s authority and traffic grows, so will the magnetism for comment spammers peddling their junk.
By implementing the techniques outlined in this guide, you can stem the spam tide to a manageable trickle. But like a mutating virus, spammers are endlessly creative in circumventing the latest safeguards.
To keep your WordPress site‘s immune system primed against new comment spam attacks:
- Keep a watchful eye on your comment moderation queue, even with anti-spam plugins installed
- Regularly audit your discussion settings to ensure permissions aren‘t too lax
- Stay updated on the latest comment spam tactics and tools via WordPress security blogs like Wordfence and Sucuri
- Consider quarterly spam plugin rotations to keep the bots guessing
Above all, don‘t let the comment spammers rattle you. With a calm mind and a stocked anti-spam arsenal, you can keep your corner of the web spam-free for years to come.
Now go forth and may your discussions be delightful and spam-less!
