This is a simple plugin designed to cut down on automated spam registrations and the emails they produce.
The idea is simple: in order to register, users have to answer a question that’s simple for anyone reading your blog, but impossible for a script being run by a spammer.
To install, simply copy stop_registration_spam.php to your Plugins directory. Enable the plugin and an options page will appear under the WordPress Settings menu.
In the settings page, enter your question (keep it short), answer (ideally very short) and a hint to display if the user gets it wrong. Save these and they’ll be used for new registrations.
I’ve been using this plugin for a few months, and it cut spam from dozens a day to none at all. Hope you find it useful. Questions etc welcome on my blog:

Honeypot Anti-Spam stops comment spam in WordPress using the honeypot technique – with no captcha, no puzzles and nothing for your visitors to solve.
Spam bots automatically fill in a hidden field that real visitors never see. The moment they do, the comment is flagged as spam. The result: cleaner comments, zero friction for genuine users and no annoying CAPTCHA.
<h4>Why Honeypot Anti-Spam?</h4>
<ul>
<li>No captcha – completely invisible to visitors, nothing to type or click.</li>
<li>Zero configuration – install, activate, done. There are no settings to touch.</li>
<li>Lightweight and fast – a tiny script with no bloat and no impact on page speed.</li>
<li>Privacy friendly – no external services, no tracking, no data leaves your site.</li>
<li>Native WordPress comments – works out of the box with the standard comment form.</li>
</ul>
<h4>How the honeypot technique works</h4>
The honeypot antispam technique adds a hidden field to your comment form via JavaScript. A legitimate visitor never sees this field and therefore never fills it in. Spam bots, however, detect it and fill it in, so the comment or submission is immediately classified as spam.
Honeypot Anti-Spam has NO options and NO configuration. To get it working you only have to install and activate it. Nothing else.
