High removal-risk signals

63/100

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 8+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 3.4.2, 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.

Release cadence

No release in a year

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

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.

    Our WordPress site runs on an iSeries and we have problems using the main caching plugins (Supercache, T3 Cache etc). All of our pages were taking up to 10 seconds to load, mostly because of the WYSIJA (Mail Poet) and Jetpack plugins. A code trace showed that WYSIJA seemed to take forever looping through POMO and MO functions. As soon as this plugin was installed the site sped up dramatically.
