Comment Blacklist Updater

72 Quality Score

Active Installs

14/30

About 1,000 active installs makes this a niche utility rather than a mainstream plugin, though its focused scope explains the modest adoption.

Update Freshness

25/25

The plugin was last updated on 2026-05-11, is tested with WordPress 7.0, and supports PHP 5.6, signalling active and forward-compatible development.

User Rating

12/15

A 96 out of 100 from 4 reviewers indicates strong satisfaction, but the tiny sample size means the rating should be read with some caution.

Support Health

8/15

Zero support threads opened and zero resolved give no signal either way, which we score as neutral rather than positive given the absence of trackable help history.

WP Compatibility

15/15

Compatibility is excellent, requiring only WordPress 4.0.1 and PHP 5.6, and being tested against the current 7.0 release.

What It Does

Comment Blacklist Updater refreshes the keywords stored under WordPress's built-in 'Discussion > Comment Blacklist' so they stay current with emerging spam patterns. The blacklist also extends to form submissions, including Contact Form 7, helping you catch junk without paying for a third-party spam service. It is a lightweight companion to the moderation tools WordPress already includes.

Who It's For

This plugin is a good fit for site owners who already use the native WordPress comment blacklist and want it to stay effective without manual upkeep. It is especially useful for small business sites, blogs, and online communities that receive form or comment spam and want a free, set-and-forget supplement to their existing defenses.

Who Should Skip It

If you are already running Akismet, CleanTalk, or a CAPTCHA/Turnstile layer on every form, this plugin adds little value because the upstream filters will catch most junk first. Sites with very low comment volume or no public forms will also see no practical benefit.

The Bottom Line

Comment Blacklist Updater is a small, well-maintained helper that does one thing and does it cheaply, making it a sensible add-on for sites already relying on WordPress's native blacklist. With only about 1,000 installs and no support-thread history, it is a low-risk pick for hobbyists and small sites but lacks the track record needed for high-stakes deployments. Overall Quality Score: 72.45/100.

Pick Akismet if you want the industry-standard, cloud-backed spam filter covering comments, trackbacks, and contact forms on high-traffic sites.

CleanTalk Anti-Spam. Spam Firewall & Bot protection 92/100

Choose CleanTalk when you need a full spam firewall that also blocks bot registrations and form submissions on membership or WooCommerce sites.

hCaptcha for WP 91/100

Go with hCaptcha if you prefer a privacy-friendly challenge layer that stops bots before they ever reach your blacklist or forms.

Simple CAPTCHA with Cloudflare Turnstile 90/100

Use Cloudflare Turnstile when you want an invisible, low-friction CAPTCHA that reduces spam without frustrating real visitors.

Database Addon for Contact Form 7 – CFDB7 88/100

Choose CFDB7 if your main need is storing and reviewing Contact Form 7 entries rather than filtering spam, since it complements rather than replaces blacklist tools.
