WordPress Zero Spam


Why force users to prove that they’re humans by filling out captchas? Let bots prove they’re not bots with the WordPress Zero Spam plugin.

WordPress Zero Spam blocks spam submissions including comments, registrations and more automatically without any config or setup. Just install, activate, and enjoy a spam-free site.

WordPress Zero Spam was initially built based on the work by David Walsh.

I have been using this plugin for contact form 7 on a few sites for several months and it works great.

I installed this on a client site, and I was pleased that it actually stopped the thousands of incoming spam messages. That's great. BUT then I got word from the client that people weren't able to post comments at all. Disabling the plugin allowed comments to get posted again. It doesn't do a lot of good to block spam if you're also blocking legitimate content. We are still looking for a solution that blocks spam and allows legitimate content to go through.
