Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
Occasionally updatedHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

How we estimate this
Assumptions
- Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product. Past 1M installs we taper the rate down: a giant free plugin’s long tail converts far worse.
- Annual price per customer. $99–$199 a year, typical for Security plugins rather than this plugin's own pricing.
- Acquisition multiple. 2x–4x annual revenue, the going range for small WordPress-plugin businesses, the typical range for a steady plugin.
- Install base. 5M–6M active installs, from our install estimate (wp.org only publishes the floor).
Inputs
- Active installs
- 5M–6M
- Category
- Security
- Pro tier
- detected (known freemium plugin with a public paid tier)
- Download trend
- volatile (a recent download spike, likely a release)

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

Omg I was getting so many fake comments everyday. Installed this and boom, it just stopped. Literally a lifesaver cz deleting them manually was a nightmare. Highly recommend!

Blocks thousands of fake comments daily. It’s a lifesaver cz my site stays clean without any effort. Setup is super easy too. Only 4 stars coz the pricing for biz sites is a bit high, but thx for the peace of mind!

It blocks many spam comments, which is helpful. But a few still pass through, and sometimes real comments look suspicious too. Good plugin, just not perfect.

It catches many spam comments, so my comment section stays cleaner. But sometimes I still need to check things manually. Good support, just not fully hands-free.
Read on wp.org ↗ - ★★★★★ denver524mo ago
It catches most spam comments for me, which saves time. Setup was simple too. A few things can still slip in, but overall it does the job well.
