Stop Spam Comments


Simple, lightweight yet effective spam comment blocker for WordPress.


  • Dead simple: no setup required, just activate it and enjoy your spam-free website.

  • Invisible by design: no captchas, no tricky questions or any other user interaction required at all.

This plugin is now also translated in: Italian. Translation help is welcome.


  1. Upload the plugin files to the WordPress /plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Done!

There is also an option in the ‘Setting’ > ‘Discussion’ menu that let you keep the blocked comments in the WordPress backend spam queue. But please note that since they are stored in the DB, if your website gets lots of spam it may affect your server load.


I activated the plugin but cannot see any changes on my website

The plugin is invisible by design. But once you activate it, hopefully you will have no more comments by spambots.

Does this plugin work in browsers with Javascript disabled?

Yes, but users with Javascript disabled (maybe <0.1% of total) will see a notice to add a special key code along their comment.

So not only spam messages won’t post, but noone can post any comment

Please, be sure your theme is using the proper comment_form() template function for displaying comments. For more see this thread.


Spam within an hour

I have several sites that I tried this on. It did not work for me, within an hour I had spam comments. My advice try it, it may work for you, but unfortunately it did not work for me.

Great independent tool

I have been using this plugin for the last two years and it does its job splendidly. The plugin blocks both user registration attempts and anonymous comments from suspicious sources. Judging by the stats, it kills more than 100,000 spam comments a year on my site. I dread the thought of doing that manually!

The “report spam to SFS” button is great!

Good Support

Plugin developer actively provide support and bug fixes for this plugin. Highly recommend this plugin to combat spam comments.
