Mimic Guard is an anti-spam plugin for WordPress mail and contact forms. It uses dynamic honeypots, submission time monitoring, and integration with major form plugins to reduce automated bot submissions.
<ul>
<li>Honeypot — Detects bots that fill hidden form fields</li>
<li>Time check — Flags submissions that are unrealistically fast after the form is shown</li>
<li>Form integration — Works with WPForms, Contact Form 7, comments, and more</li>
<li>Page caching — Optional AJAX honeypot injection when HTML is cached</li>
<li>Privacy — Optional IP anonymization when logging events</li>
</ul>
Configure minimum submission time, token lifetime, log list size, and more from the admin screens.

Mimic Guard

Block spam submissions with honeypot fields and submission timing checks.

keith_wp

Blocks spam signups by adding an invisible field to your registration and login forms, and switching its id with the real username or email form field.
When spam bots blindly fill the “required” fake field in, WP will redirect them to an error message and not let them register or login.
No 3rd party service, no intrusive captchas.

SpamPot

Adds a honeypot form field on the registration and login pages to trap spammers.
