Biggest opportunity: “anti captcha”, “anti spam” and “blocker” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

How it's measured →1.1%
of downloads still active
At least 1K of 88.4K lifetime downloads are still running, above its category: the median Search plugin keeps 0.7%, across 645 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Search 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 8+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.0.0, well behind 6.8.

This plugin does not work in recent WordPress versions. It filters out every comment as spam, also those by humans, not bots.

For my personnal need I extended the anti-captcha plugin simply by adding an add_action() and the corresponding function : now my booking forms are protected and it works like a charm, out of the box. Thank you !

I have this plugin installed for a couple of years now, and only need to delete one or two spam comments that slip through. No captcha.
