A lightweight Formidable Pro anti-spam add-on that requires no interaction with the user.

of downloads still active
At least 60 of 2.6K lifetime downloads are still running, above its category: the median Security plugin keeps 1.4%, across 997 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 11+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.0.38, well behind 6.8.

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.

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.
- 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. 60–70 active installs, from our install estimate (wp.org only publishes the floor).
Inputs
- Active installs

- Category

- Pro tier
- detected (description mentions a Pro or Premium version)
- Download trend
- steady (30d downloads flat vs prior 30d)

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.
