Removal-risk signals

53/100

Maintenance 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 3+ years — the top precursor to removal once a vulnerability is found.
  • Falling behind WordPress. Tested up to WordPress 6.0.14.

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 often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    Thank you so much for this plugin. I didn’t notice the email attack on my client’s web site until 490,000 messages had been blocked and quite a few had gotten through. The number was increasing by about 3000 per minute, and after enabling this plugin, the incoming messages were just STOPPED, INSTANTLY.

    Works like a charm. It doesn’t slow down the page at all and catches all spam with incredible accuracy—I haven’t had to delete a single spammy message since installing it. Excellent work!
