WordPress Spam Is Out of Control

If any of this sounds familiar, you're not alone.

Bot Floods

Automated bots hammer wp-comments-post.php and the REST API around the clock, filling your database with junk and slowing your site.

Manual Moderation Burnout

Hours spent reviewing, deleting, and banning spammers that keep coming back under new IPs and usernames.

Akismet Isn't Enough

Akismet catches some spam but lets sophisticated attacks through, still charges per-site, and does nothing to stop bots at the endpoint level.

A Complete Anti-Spam Arsenal

Multiple layers of protection that work together to stop spam before it reaches your site.

Trainable Naive-Bayes Classifier

Shared global model plus your own isolated classifier that learns from your moderation actions. Gets smarter every day.

Optionally AI-Powered Detection

Enable AI-powered content analysis to catch sophisticated spam that rule-based systems miss. Entirely optional — if you prefer not to share comment data with third-party providers, the built-in classifiers have you covered.

Trust Factor System

Automatically scores commenters based on behavior history. Trusted users post freely while new accounts face higher scrutiny.

Repeated Message Detection

Detects and blocks duplicate or near-duplicate comments across your site, stopping copy-paste spam campaigns instantly.

Bad Words & Profanity Filter

Configurable word lists that automatically flag or block comments containing profanity, slurs, or custom banned terms.

Bot Endpoint Blocking

Bots targeting wp-comments-post.php and the WordPress REST API hit a dead end. Comments flow through FastComments' protected infrastructure instead.

Frequently Asked Questions

We've compiled answers to some of the most common questions to help you get started.!

Can I migrate my existing WordPress comments?

Yes. The FastComments WordPress plugin includes a one-click import that brings over all your existing comments, including nested threads, author information, and timestamps. The migration typically completes in under a minute for most sites.

How does FastComments compare to Akismet?

Akismet is a spam filter that sits on top of the default WordPress comment system. FastComments replaces the entire comment system with a purpose-built platform that includes multiple layers of spam protection (AI classifiers, trust scoring, bot blocking, profanity filters), plus features like real-time commenting, SSO, and detailed moderation tools. It's a complete solution, not just a filter.

Will switching affect my SEO?

No. FastComments syncs comments back to your WordPress database daily, so search engines continue to index your comment content. Comments are also rendered in a way that is accessible to crawlers.

Does it work with WooCommerce?

Yes. FastComments fully supports WooCommerce product reviews and comment threads. Spam protection applies to all comment types across your store.

Can I use it on a WordPress multi-site network?

Yes. Since WordPress uses numeric page IDs, you should create a separate tenant in your FastComments account for each site to keep comments separated. Moderation is centralized across all tenants, and each site gets full spam protection.

Will FastComments slow down my site?

No. FastComments loads asynchronously and is served from a global CDN. It's typically faster than the default WordPress comment system because it offloads comment rendering and spam processing from your server.

Stop WordPress Comment Spam. For Good.
