HumanCaptcha by Outerbridge

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 92% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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.

   Une excellente et simple extension de captcha au plan de l’accessibilité pour les aveugles tant en visiteurs qu’en administrateur ! J’en étais vraiment ravi jusqu’à ce que récemment, je me suis aperçus d’une faille de sécurité majeure dans la page “santé du ste” de WordPress : Une session PHP a été créée par un appel de fonction session_start(). Cela interfère avec l’API REST et les requêtes de boucle (loopback). La session devrait être fermée par session_write_close() avant d’effectuer toute requête HTTP. La désactivation de toutes extensions de mon site pour les réactiver une à une ont imparablement diagnostiqué Human Captcha comme responable de cette faiblesse.Je comprends fort bien la réponse du développeur joint par courriel,qui m’indique être trop occupé par des activités rémunératrices pour s’en occuper, sauf si j’accepte de financer ce développement. Moi, quand je suis trop occuper, ce n’est pas un financement qui pourra m’occuper moins !J”espère que les 400 utilisateurs de l’extension que nous sommes n’auront pas à en pâtir !

   I have tried google recaptcha but somehow my site was still being spam until I change to this human captcha, no more spam user, comment….etc….all gone. Thank you very much for this great plugin and its author. PS: I used this plugin over 4 years. After a long time using and now I come back to review. ))) This topic was modified 3 years, 7 months ago by sachsongngu.

   Extremely simple and effective plug-in to cut ALL spam comments. This is just what I wanted: simple questions in the language my content is to block bots from forms on my site. Had a bit of teething trouble when I took it up, the language has characters it didn’t support correctly in combination with numbers but in the end the developer resolved this very fast. Could do with a little more features but KISS.

   Three thumbs up for ease of installation, plus a another thumb up for creativity. I installed this plugin on three sites that cater to people who like to think, so being able to customize questions that are a little thought-provoking is a real treat. So far, everything seems to be working OK. David W. Blomstrom

   So I really wanted to like this plugin. It does what it’s supposed to do and does it well. I like the simple options to control where it appears as well as make my own captcha questions. However, The settings for this plugin appear under the Plugins menu item in the admin rather than the typical Settings menu where most would appear. This is extremely abnormal and easy to forget. Worse though, it made it completely unusable for me since I run a multisite network that hides the Plugins menu item in the admin areas. It makes it impossible to reach this plugins settings. So, can’t use it because of this unusual functionality.

   Easy to install and set up. The is a better captcha for a low vision person, because they don’t have to try to interpret a fuzzy image with numbers or letters. Great captcha for people using screen readers.
