Stop Referrer Spam


This plugin blocks referrer spam that you see in your page statistics. This problem is also widely known as “spam referrer attacks”.

The biggest list of spammers

Plugin uses the biggest public list of URLs that are considered as a spamming services; over 1100 URLs right now! List is provided by Piwik, the biggest open source analytics system and you can find it here; you can also contribute to that list by adding your own urls.

Custom URLs

Yep, you can add your own URLs to blacklist! In a flash! So easy…

No annoying updates!

This plugin uses service located on our servers to update the list of spammers, hence you do not have to update the plugin itself whenever list is updated.

No need of an account!

As it is said before, this plugin uses endpoint to get the actual list. That endpoint points to author’s server (, but there is no need of an account to use it. And no worries, this plugin do not collect any data about the users 🙂


You can see the current list of blocked websites in the admin panel, under “Settings/Referral Spam”. There is also time of the next update. That is it! No configuration needed! 🙂

Free of any charges!

It is completely free! Enjoy! 🙂


  • Simple Referrer SPAM admin panel

  • upload all plugin files to wp-content/plugins/

Does the plugin block **all** spam traffic?

Well, no. Unfortunately some of the spam services uses techniques that makes them unrecognisable, but it still blocks nearly all of them 🙂

Does the plugin use any of my data?

No, not at all.

Do I need an account to use it?

Nope, no need of an account.

Can I put my own URLs that I want to block?

Yes you can! And each URL will be a wildcard. That means, if you put on the list, it will block all the trafic from that domain + sub-domains on any level.


Awesome plugin

It works. If you are expecting it to clean up everything then you are expecting too much. It does exactly what it says it should. It works great and stops a LOT of the spam. Using this and some other fixes in my Google Analytics has made my data better.


Dzięki za ten plugin. Zobaczymy jak wpłynie na wyniki analiz google

Still Lets Spam Through

I have no idea where the other reviews are getting their results from (if they are even genuine reviews). It still lets referral spam through even after added to the blacklist. So many examples but a specific one is which was already entered into the blacklist manually. Otherwise I'm not even sure what kind of blacklist it is accessing because I was getting TONS of referral spam with the plugin active and I had to enter referral URLs manually.

It works in 2018

Yes, it works! One of the few anti referrer spam plugins that actually works. Does NOT need .htaccess. Works perfectly and it also blocked a lot of click-fraud. That's just the icing on the cake.
