Stop Comment Spam With Spam Free WordPress

in Blog

Todd Lahman recently contacted me about his new plugin Spam Free WordPress which promises to be the only comment spam blocking plugin that blocks 100% of the automated spam with zero false positives. He initially released the plugin as a premium plugin however he has since released the plugin for free.

In order to test the plugin on WP Mods, Todd advised me to disable all other comment spam plugins including Akismet so that I get the best results. Over the last week I have been using Spam Free WordPress on WP Mods and it seems to work really well. WP Mods hasn’t really had a major problem with comment spam as most comments from spam scripts got caught by Akismet and placed in the spam folder. Every now and then a few would slip through though but that hasn’t happened as yet with Spam Free WordPress (admittedly, 7 days isn’t really a long enough time to test a plugin of this nature).

The plugin uses an anonymous password authentication to prevent comment spam. Every post is assigned a secret password. It is only generated after the first time someone visits the page and a new password is generated after every comment. I much prefer this to the CAPTCHA system, which regularly frustrates visitors with images that are impossible to read.

The plugin has a local blacklist though you can link to an external blacklist file as well. This is useful for blocking IP addresses of known spammers.

I had Spam Free WordPress installed for about 5 days. I then went back to using Akismet to see if I noticed any major differences and then reactivated Spam Free WordPress again (version 1.3.7). As I mentioned previously, 7 days isn’t a long time to test a plugin nature of this kind. I am however fairly impressed with the number of comments it is blocking. Whether Spam Free WordPress is the plugin to replace Akismet, only time will tell, however it seems to be a real contender and I see no reason for me not to keep using it for the foreseeable future.

I encourage you all to try it out if you are having problems with comment spam.

    I don’t understand… If the Spam Free WordPress plugin blocks spam and presumably bots by using a password for each comment, then why would you need to use a blocklist to ban users by IP to essentially do the same thing — block comment spam?

    What about human spammers? How does it detect/stop them?

    The SiteBrains Interactive Spam Blocker is also available as a free WP Plugin at

    It uses encryption to sign and validate each post to stop bots but also analyzes the embedded urls in comments for spam target sites/content. It doesn’t require a block list of any type.

    haha. I know what you mean. I really do hate captchas sometimes. I’ve got good eyesight and even I struggle with them frequently.

    Trying it out myself. Really like it so far. I like the use of a simple copy/paste; I swear, I’m developing eye strain from deciphering Web site captchas.
