Stop Spammers


Stop spam emails, spam comments, spam registration, and spam bots in general.

Created with a lot of hard work and maintained by Keith P. Graham (from 2010-2017). Thank you Keith.

Maintained (because I love this plugin and want to keep it alive) by myself, Bryan Hadaway (since 2017).

Go to Plugins > Add New from your WP admin menu, search for Stop Spammers, install, and activate.


  1. Download the plugin and unzip it.
  2. Upload the plugin folder to your wp-content/plugins folder.
  3. Activate the plugin from the plugins page in the admin.

Either way, Stop Spammers works right out-of-the-box, without needing to adjust any settings. However, if you need it, there are many settings that can be adjusted.

We were getting about 10-20 bogus site registrations per day. Akismet didn't stop them, neither did other plugs we tried. This one works! No more going through our users to dump the daily bunch of spammers.

Boy does this thing work! I used to get 30-40 spam comments a week even using Aksimet. I installed this thing and now I get NO spam comments at all! Does it's job and does it perfectly. Thank you!

I would love to add this plugin to my WP sites but it cannot handle a RFC 1918 private IPv4 address. All my WP sites run in containers behind other containerized proxy-servers in a private docker network. The plugin only sees the WP container's private IP address from the docker network and complains that it cannot function. I would love to be able to provide the public IP address manually, or use the domain name but there is no option for that.

To Whom This May Concern, We have been using this plugin for sometime now and works great and sometimes too great, lol. I have a question, is there a way to auto send out an email to the person letting them know they have been added to Allow List? If there is it would be great to have, that way I dont have to send out 5-10 emails a week, lol. Thank you, RALLInspired.

I have Been using wordpress for a long time and this is one of the greatest plug-ins I have found. I imagine the only people giving it a bad review are probably spammers LOL. This is definitely one of the most slept on plug-ins or WordPress. The amount of thought and a effort put in is quite amazing thank you Keith and Bryan. It was the quickest and best fix for spam bot registrations on my WooCommerce site. It also keeps you well informed on other aspects of security and plays well with iThemes Security so i'm finally sleeping good at night.
