Anti-Spam Protection – No API Key, GDPR Friendly

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

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

Share of active installs on each version of this plugin · 57% 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.

   I’ve tried several anti-spam plugins over the years, but Anti-Spam Protection, No CAPTCHA, No API Key has been one of the easiest and most effective solutions I’ve used. Installation took only a few minutes, and it started blocking spam immediately without requiring complicated setup, CAPTCHA challenges, or third-party API keys. That’s exactly what I was looking for—a plugin that simply works without adding unnecessary complexity for my visitors. I especially appreciate that it stays out of the way. My contact forms remain clean and user-friendly, while the spam quietly disappears in the background. It’s lightweight, reliable, and doesn’t feel bloated with features I’ll never use. As someone who would rather spend time creating content than deleting spam, this plugin has been a huge time saver. If you’re looking for a straightforward, effective anti-spam solution for WordPress, I highly recommend giving it a try. I’d also like to thank Alan for the excellent support. On the few occasions I had questions, he responded quickly, professionally, and genuinely wanted to help. It’s refreshing to find a developer who not only builds a solid plugin but also stands behind it. Thank you for creating a product that simply works. Fred V

   I remember the times I was bombarded with hundreds and thousands of quite inapropriate spam on my numerous WordPress sites. It took a lot of time, energy, and patience to clear that up. Then, I found Anti-Spam by Fullworks. I couldn’t believe such a plugin could be free AND effective. Yet, for years I used the free version of Anti-Spam by Fullworks on my more than 25 educational WordPress sites with no issue whatsoever. Instead of dealing with spam, I used my extra time on building content. I liked this plugin so much that I now have the paid version on all my sites.

   Unlike Akismet which needs an API key and a whole load of limitations this one just works. And works really well. Highly recommended

   I had a site with multiple spam entries and I’ve tried a couple of options. None had the efficiency of this plugin. I highly recommend

   Not bloated with features. But it seems to have everything that one needs for an antispam plugin. Very simple to install and to use. Affordable too. And support answers questions in a prompt and friendly way. Just make sure to use a contact form that is compatible with Fullworks Anti Spam, in order for the plugin to cover your site against spam fully (including human spam and not only bots). In case your contact form is not on the list, ask support – in some cases, they can find a solution.

   Works with latest release and I think this is the only plugin that works with AJAX lazy loaded comments. Developer fixed issue that evening. Wow! This topic was modified 4 years, 5 months ago by itsryu. This topic was modified 4 years, 5 months ago by itsryu.
