Editor’s note (April 2026): This article is part of the Blog Herald’s editorial archives. Originally published in October 2013, it has been revised and updated to ensure accuracy and relevance for today’s readers.
As soon as your blog starts getting traffic, it attracts something else: spam. Comment spam. Spam back. Registration spam. Form spam. The methods have evolved a lot since the early days of blogging, but the main problem hasn’t. Automated bots search the web for open comment sections, contact forms and registration pages – and WordPress, provides more than 40% of the internetis a constant target.
What has changed since the early 2010s is the sophistication of attacks. Back then, the basic comment filter was often enough. Today’s spambots are smarter, faster, and sometimes indistinguishable from legitimate traffic on the surface. Link spamming has become an industry, and an unsecured blog comment section can be overrun within hours of going live.
The good news: the plugin ecosystem has matured significantly. A handful of well-maintained tools now reliably handle much of this work, and understanding why each works the way it does will help you make smarter choices for your site.
Akismet: still the main, but not the ceiling
Akismet remains the starting point for almost every WordPress installation. Comes with WordPress by default, maintained by Automattic and more 6 million active installs processes many spam signals on the internet. This collective learning is part of what makes it effective – it’s essentially crowd-sourced spam intelligence.
The pricing structure has changed over the years. It’s free for personal blogs, but commercial sites require a paid plan (starting at $10/month starting in 2025). For many bloggers running hobby sites or small publications, the free tier is sufficient. For anyone running a business blog or monetized content site, it’s reasonable to include Akismet in your core operating costs.
Fair warning: Akismet is reactive by design. Identifies and filters spam after the fact. It doesn’t prevent bots from hitting your form in the first place. This distinction is important for high-traffic sites – each blocked submission still consumes server resources.
Antispam Bee: a privacy-conscious alternative
Antispam Bee has quietly become one of the most respected spam solutions in the WordPress ecosystem, now holding a 4.8 star rating with 225+ reviews and over 700,000 active installs. It’s not just the feature set that sets it apart, it’s the philosophy behind it.
Unlike Akismet, Antispam Bee does not send commenter data to an external server for processing. All spam checks are done locally. This is a meaningful distinction for bloggers operating under GDPR or other privacy regulations, or simply for those who are cautious about data management.
Functionally, it offers more granular control than Akismet: country-based blocking, language filtering, integration with Project Honey Pot (a community database that tracks fraud and abuse), and the ability to flag comments from known spam IPs before they even enter the queue. The German-language plugin page, which once confused some users, has long since been updated to English.
Something worth noting: Antispam Bee can work aggressively if configured incorrectly. Some legitimate international commentators have been caught in country-based blocks. Take ten minutes to review the settings before going live.
The honeypot technique: invisible friction that actually works
One of the more elegant anti-spam approaches – and still underused – is the honeypot method. Plugins like NoSpamNX have helped popularize the idea among bloggers who aren’t technical enough to do it manually.
The principle is simple: add invisible form fields that human users never see and never fill out. Spam bots that scan and blindly complete form fields autofill them. When the plugin detects a completed hidden field, it records or rejects the submission.
The appeal of this approach is that it adds zero friction for real readers. No CAPTCHAs to solve, no math puzzles, no checkboxes. It is completely passive. For bloggers who are seeing a drop in comment engagements due to aggressive review gates, honeypot plugins are worth testing as an alternative or in addition to other methods.
NoSpamNX, the plugin covered in the original version of this article, is no longer actively maintained. But the technique lives on in several actively developed plugins, and many comprehensive spam suites now include honeypot logic as a standard feature layer.
What happened to trackback spam – and what replaced it
Back in 2013, spam was a real daily concern for anyone running a medium-sized blog. The Simple Trackback Validation plugin existed specifically to solve it. Today, trackbacks and pingbacks are largely deprecated – most modern WordPress installations turn them off by default, and the SEO value that once made them worth the game has diminished significantly.
This does not mean that the spam problem has gone elsewhere. This happened. Registration spam (fake accounts created en masse by bots) is now an increasingly common attack vector for any blog that allows user registration. Spam forms via contact pages and subscription forms have also increased as bots target email capture forms to get addresses onto mailing lists.
Livefyre, the original list-making commenting platform for internal spam protection, shut down in 2017 after Salesforce acquired and discontinued the service. This is a useful reminder that third-party commenting systems carry platform risk – when the provider goes, your comment history and moderation history goes with it.
Building a layered approach
The bloggers who deal with spam most effectively don’t rely on a single plugin. They are complementary tools: Akismet or Antispam Bee for comment filtering, a honeypot plugin for form protection or a security suite, or a custom registration filter if you run a membership site.
It’s worth checking your WordPress comment settings directly. Requiring commenters to have a previously approved comment before the next one is published, saving comments with multiple links for moderation, and closing comments to posts older than a certain date — these native WordPress options really work without any additional plugins.
Spam protection is maintenance, not installation. The landscape changes, bots adapt, and plugins that work well in 2020 may need to be updated or replaced by 2026. It takes ten minutes every now and then to check your active installations for updates and review your spam queue – and that ten minutes preserves years of legitimate chatter on your site.
The goal has never been to create a frictionless experience for everyone who visits. It’s really about creating a frictionless experience for the readers out there.
