How It Works

Most of the spam hitting your site originates from bots, but quite a bit comes from humans too. This plugin works like a firewall to ensure that your commenters are in fact, human, and that those humans aren’t spamming you.

Two Layers of Spam Blocking

There are two layers of leading edge anti-spam protection that work together to block both automated (spambots) and human spam:

  1. The JavaScript/Cookies Anti-Spam Layer
  2. The Algorithmic Anti-Spam Layer

The first anti-spam layer uses a dynamic combination of JavaScript and cookies to weed out the humans from spambots, preventing 100% of automated spam from ever getting to your site. Even if bot authors could engineer a way to break through the JavaScript/Cookies Anti-Spam Layer, the Algorithmic Anti-Spam Layer would still stop almost all of the spam that the JavaScript Layer blocks, and provides close to a fully redundant backstop. This JavaScript Anti-Spam Layer utilizes multiple randomly generated keys, and is algorithmically enhanced to ensure that spambots won’t beat it. The powerful Algorithmic Anti-Spam Layer consists of over 100 advanced filters, and eliminates trackback spam and most human spam as well. And, it does all that without hindering legitimate comments, trackbacks, contact forms, or registrations.

No More Wasted Time Sifting Through the Comment Spam Queue

This type of solution works invisibly in the background, with no inconveniences. You won’t have to waste valuable time sifting through a spam queue any more, because there won’t be anything there.

WP-SpamShield is different from other anti-spam plugins in that it BLOCKS spam at the front door of your site and doesn’t allow it into the WordPress database at all. Many other anti-spam plugins simply label a comment as spam, leaving you to sort through a spam queue, which wastes your valuable time. WP-SpamShield will give you back your time!

Improves User-Friendliness of Your Website

If you want to improve the user-friendliness of your site, this is THE anti-spam plugin you want. After all, why should your users have to prove they are human? Since your users won’t be inconvenienced by outdated and frustrating anti-spam methods, you will provide a smoother, trouble-free experience for your website users, which leads to improved readership, ad revenue, sales, or other types of conversion, and therefore greater success for your website.

Improves Security

Not allowing spam into the database improves security by potentially preventing SQL injection, DDoS, and XSS exploit attacks through automated spam comment submissions. WP-SpamShield fixes the security issues inherent to Pingbacks, and prevents Pingback-based DDoS attacks. As part of the Miscellaneous Form Spam Protection, the plugin protects against XML-RPC brute force amplification attacks. The plugin also has several other features that improve security, such as blocking certain potentially dangerous URLs in spam comment submissions, and limiting comment size to 15kb. (15kb of text is roughly the equivalent of 3 typed pages in Microsoft Word, single-spaced, so that’s more than enough for even the longest of comments.) See this blog post for more info.

Helps Improve Overall Website Performance

The plugin helps keep your WordPress database slimmer and more efficient (keeping your site running faster in the long term) by not allowing the thousands upon thousands of spam comments into it, which could bloat the database and potentially corrupt it. Keeping your database lean is extremely important, because bloated databases result in much longer query times and increased server load, slowing down a site dramatically even for simple functions. If website performance is important to you, then you definitely want an anti-spam plugin like WP-SpamShield instead of a plugin that uses a spam queue. See this FAQ for more detailed info.

ZERO False Positives

It does all this with ZERO false positives, because of the method used to block spam. Notice we didn’t say a “low false positive rate” – we said ZERO false positives. If a comment/contact form/registration gets blocked as spam, the user is given instant feedback and has a chance to correct their comment/contact form/registration/etc and try again, which means there cannot be false positives. This leads to fewer frustrated website visitors, and less work for you. We are committed to keeping the promise of zero false positives.

100% Pingback/Trackback Validation and Anti-Spam

The trackback validation contains a filter that compares the client IP address of the incoming trackbacks and pingbacks against the IP address of the server where the link is supposedly coming from. If they don’t come from the same server, then it is guaranteed spam, without fail. This alone eliminates more than 99.99% of trackback & pingback spam. Trackback spammers don’t send spam out from the same server where their clients’ websites reside. There are algorithmic anti-spam filters in place to ensure 100% trackback/pingback spam blocking. You can be confident that only legitimate trackbacks and pingbacks will get through.

Includes a Spam-Free Contact Form, and Anti-Spam for Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms, and Most Other Forms

Includes drop-in spam-free contact form, with easy one-click installation. Easy to use – no configuration necessary, but you can configure it if you like. (See Installation for info.) WP-SpamShield also includes automatic anti-spam protection for Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms, Fast Secure Contact Forms, Formidable Forms, and more. (You don’t have to do a thing…just add your Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms, or other forms to your site, and they will automatically be protected.) It will automatically protect most forms on your WordPress site from automated spam, even if they are not listed here.

WordPress Registration Anti-Spam

The plugin also includes powerful protection from user registration spam. Once you install WP-SpamShield, you don’t have to worry about bots or spammy users signing up any more. (Note: This protects almost all registration forms, including the WordPress default registration form, and registration forms for bbPress, BuddyPress, WooCommerce, s2Member, WP-Members, and many more. See this FAQ for more info.

Stops Email Harvesters

The plugin has a feature to thwart email harvesting bots and keep them from scraping your site for email addresses. (Which helps reduce spam in your email inbox.) The plugin automatically obfuscates plain text email addresses and mailto links in your website content by encoding them into HTML entities (hexadecimal and decimal character codes that look like gibberish to harvesters, but render the email addresses perfectly in a browser). It protects email addresses on pages, posts, comments, excerpts, and text widgets.

Why Not Just Use a CAPTCHA-Based Anti-Spam Method?

The concept of using a CAPTCHA as an anti-spam solution in this modern day and age is flawed for several reasons:

  1. It’s an outdated concept that has far outlived its usefulness, and was originally developed before user-friendliness was a high priority.
  2. It goes in the exact opposite direction of user-friendly design principles. Think about it. Users of your website have to type in numbers and letters obscured by squiggly lines and symbols, only to be told they are wrong several times, even after typing in the correct answer. This is proven to hurt website business and revenue because of the negative feelings it causes. People simply don’t like CAPTCHAs.
  3. It is not the user’s responsibility to separate humans from bots, or to stop spam; it’s the web developer’s responsibility. Even if the CAPTCHA is simple, and all the user has to do is click a button, it is still annoying and unnecessary. It’s one extra step that you are putting between your user and their end goal.
  4. CAPTCHAs can be defeated. In fact, bots have been cracking CAPTCHAs since 2008. The only benefit of a CAPTCHA was that it was considered to be unbeatable by bots. That day is long past.
  5. Why use a CAPTCHA when there are better solutions that don’t inconvenience your website users?

Optimized and Scalable – Won’t Slow Down Your Site

This plugin has an extremely low overhead and won’t slow down your site, unlike some other anti-spam plugins. Each of the filters in the plugin have been benchmarked, and when processing comments for spam, the fastest filters are put at the front of the stack. Once a comment tests positive for spam, the testing process terminates and will not engage the remaining filters. Additionally, as mentioned above, by keeping spam out of the WordPress database altogether, WP-SpamShield helps keep your database slimmer and more efficient, which in turn helps keep your site running faster. This efficiency helps keep the server load down, and helps improve the overall performance of your site. WP-SpamShield is optimized to work well with all major caching plugins.

Faster than the Cloud

Speaking of scalability, WP-SpamShield can kill spam faster than any cloud-based anti-spam solution. Cloud-based anti-spam plugins are inherently slower at processing spam because they have to connect to an external server to check the spam status, which in turn will increase your site’s server load. With WP-SpamShield, all anti-spam processing happens directly on your website’s server, with lightning speed.

Free for Commercial and Personal Websites

No cost, no hidden fees. This powerful anti-spam plugin is free for both Commercial and Personal use. If you find that WP-SpamShield benefits you, and you’re so inclined, then feel free to make a donation.

Responsive and Helpful Tech Support

If you have any issues with the plugin, we are here to help. Simply submit a support request at the WP-SpamShield Support Page, and we’ll help you diagnose and fix the issue quickly. Don’t take our word for it though – look through our plugin ratings/reviews and notice the high percentage of resolved support threads and satisfied users.

Additional Features

  1. Now WP-SpamShield provides automatic anti-spam protection for: Contact Form 7 forms, Gravity Forms, Ninja Forms, JetPack Contact Forms; BuddyPress, bbPress and WooCommerce registration forms; Mailchimp signup forms; almost all other WordPress forms; and almost all registration forms!
  2. As of version 1.9.2, WP-SpamShield protects JetPack Comments from spam. (Making it one of the few anti-spam plugins that works with JetPack Comments.)
  3. A counter on your dashboard to keep track of all the spam it’s blocking. The numbers will show how effective this plugin is.
  4. See what’s been blocked with “Blocked Comment Logging Mode”, a temporary diagnostic mode that logs blocked spam (comments, trackbacks, registrations, and contact form submissions) for 7 days, then turns off automatically. If you want to see what spam has been blocked, or verify that everything is working, turn this on and see what WP-SpamShield is protecting your site from.
  5. Multiple languages available and more on the way. Currently includes Dutch (nl_NL), French (fr_FR), German (de_DE), Indonesian (id_ID), Italian (it_IT), and Serbian (sr_RS) translations. Ready for translation into other languages.
  6. Easy to install – truly plug and play. Just upload and activate. (Installation Status on the plugin admin page to let you know if plugin is installed correctly.)
  7. Compatible with, and optimized for all major cache plugins, including WP Super Cache and many others. Not all anti-spam plugins can say that.
  8. Display your blocked spam stats on your site. Customizable widgets for graphic counters to display spam stats, in multiple colors, sizes and options.
  9. Works in WordPress Multisite as well. (See the related FAQ for details.)
  10. Enhanced Comment Blacklist option. Instead of just sending comments to moderation as with WordPress’s default Comment Blacklist functionality, with this turned on, anything that matches a string in the blacklist will be completely blocked. Block specific human spammers by IP, email address, or a number of other options. The Enhanced Comment Blacklist has some improvements over the default WordPress blacklist functionality, and adds a link in the comment & contact form notification emails that will let you blacklist a spammer’s IP with one click. It also provides some advanced custom options for blocking spam on everything else that WP-SpamShield protects.
  11. WP-SpamShield Whitelist option. Allows you to specify certain users who you want to let bypass the antispam filters.
  12. This plugin is legal to use in Germany and the EU, and does not violate European privacy laws. It does not use any type of cloud-based service, spam data is not transmitted from your server to any other server, and all anti-spam processing happens directly on your website’s server.
  13. A truly plug and play replacement and upgrade for WP-SpamFree. (This plugin is a far more advanced fork of WP-SpamFree with dramatically improved page load speed, security, and spam blocking power, by its original author.) It will import your old data from WP-SpamFree automatically upon installation and activation, and features you were using on your site previously such as contact forms and spam stats will continue to work without any changes to pages, posts, or theme.

  2. Click Choose File and find wp-spamshield.zip on your computer’s hard drive.

  3. Click Install Now.

  4. Click Activate Plugin to activate the plugin (or you can do this on the Plugins page).

Option 3: Install .zip file through an FTP Client (Recommended for Advanced Users Only)

  1. After downloading, unzip file and use an FTP client to upload the enclosed wp-spamshield directory to your WordPress plugins directory (usually /wp-content/plugins/) on your web server.

  2. Go to your Plugins page in the WordPress Admin Dashboard, and find this plugin in the list.

  3. Click Activate to activate the plugin.

Next Steps After Installation

  1. Check to make sure the plugin is installed properly. Many support requests for this plugin originate from improper installation and can be easily prevented. To check proper installation status, go to the WP-SpamShield page in your Admin. It’s a sub-menu link under the Settings. Go the the ‘Installation Status’ area near the top and it will tell you if the plugin is installed correctly. If it tells you that the plugin is not installed correctly, please double-check what directory you have installed WP-SpamShield in, delete any WP-SpamShield files you have uploaded to your server, re-read the Installation Instructions, and start the Installation process over. If it is installed correctly, then move on to the next step.

  2. Select the desired plugin configuration options. Take a look at the WP-SpamShield Settings page in your WordPress site, and familiarize yourself with the different settings available. Many times when users have an issue, they simply haven’t checked the settings to see if they can enable or disable a certain feature.

  3. If you are using front-end anti-spam plugins (CAPTCHAs, challenge questions, etc), be sure they are disabled since there’s no longer a need for them, and these could likely conflict. (Back-end antispam plugins like Akismet are fine, although unnecessary.)

  4. Install a contact form if you like. (See “Adding a Contact Form to Your Blog” below)

  5. If you’d like to test if everything is working, please see the beginning section of the Troubleshooting Guide for more info.

  6. If you are using an e-commerce plugin on your site, run a test transaction to make sure everything runs smoothly. If you have any issue with a payment gateway getting blocked, simply go to your WP-SpamShield settings and use the option “Disable anti-spam for miscellaneous forms”, and it will take care of the issue. (We have made every effort to whitelist all of these on major plugins, but in some rare occasions a problem will arise.) If you do have any issues, please submit a support request and we will be happy to help.

You’re done! Sit back and see what it feels like to live without blog comment spam, trackback spam, contact form spam, and registration spam!

NOTE: If you’re using a caching plugin, you will need to clear the plugin’s cache after you install WP-SpamShield. It’s a good practice to clear the cache after updating plugins as well.

Displaying Stats on Your Blog

Want to show off your blocked spam stats on your site and tell others about WP-SpamShield? It’s easy, just add a widget and drag and drop it where you like, in several color and size options. You have a choice of the regular size counters in 5 colors, the small counter in 5 colors, or the End Blog Spam graphic. ( </BLOGSPAM> )

There is also a customizable widget that has a number of color and style options, including a custom color chooser.

Now you can show spam stats on your blog without knowing any code.

Go to your WordPress Admin -> Appearance -> Widgets. Choose one of the following WP-SpamShield Widgets and choose your options:

  • WP-SpamShield Counter – Custom: Show how much spam is being blocked by WP-SpamShield. This is a very customizable widget with options for color and style, including a custom color chooser.
  • WP-SpamShield Counter – Graphic: Show how much spam is being blocked by WP-SpamShield. This widget provides a spam counter graphic that lets you choose what color and size you prefer.
  • End Blog Spam: Let others know how they can help end blog spam. ( </BLOGSPAM> )

There are a few visual examples of the widgets on the Screenshots page.

You can also add shortcodes to your pages and posts, and PHP code to your theme. For more info see the plugin documentation section on Displaying Spam Stats on Your Blog.

Adding a Contact Form to Your Blog

First create a distinct page (not post) where you want to have your contact form. Then, go into the editor and click the tab for the “Text” editor (not “Visual” editor). Then click the button that says “WPSS Contact Form”. It’s that easy. You can also manually insert the following shortcode if you prefer: [spamshieldcontact]

The page you place the contact form on should have its own URL, and not be used on the homepage of your site. It also cannot be implemented as part of a widget or theme element, such as a footer, sidebar, etc.

There is no need to configure the form. It allows you to simply drop it into the page you want to install it on. However, there are a few basic configuration options. You can choose whether or not to include Phone and Website fields, whether they should be required, add a drop down menu with up to 10 options, set the width and height of the Message box, set the minimum message length, set the form recipient, enter a custom message to be displayed upon successful contact form submission, and choose whether or not to include user technical data in the email.

As of version 1.8.9.9 WP-SpamShield also includes automatic anti-spam protection for Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms, Fast Secure Contact Forms, Formidable Forms, Mailchimp, and most others. (You don’t have to do anything…just add your Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms, Mailchimp signup, and other forms to your site, and they will automatically be protected from spam.) It will now automatically protect most forms on your WordPress site from spam, even if they are not specifically listed here.

Please visit the plugin documentation for more info on contact form installation and use.

Reseñas

One of my go-to plugins

I began using this plugin a few years ago after having problems with another one. It does a great job of stopping spam comments, but I love that it also prevents email harvesting as well as filtering spammy form submissions.

Fabulous!

I use this plugin on all my sites, it stops spam signups and comments and form submissions without any stress at all.

Amazing support

Spamshield has been a helpful plugin in preventing bots from submitting spam to dozens of our forms. In addition, the one time I’ve reached out to support was an extremely positive experience. You do need to go to the plugin’s website, read through the FAQs, and go through their troubleshooting process first. They give easy to follow step by step instructions. Since we were still having issues, I submitted a support ticket along with their requested extra debugging information, and they not only tracked down the problem, they released an update to the plugin overnight that they believe will fix the problem. That’s incredible support for any plugin, let alone a free one. 5 stars, we’ll definitely keep using this to protect our sites.

1.9.8.8

released 06/20/16

  • Made various code enhancements and improvements.

  • Added protection against XML-RPC brute force amplification attacks. Added a filter to the Miscellaneous Form Spam Protection to block XML-RPC and REST requests from servers using spoofed Reverse DNS entries (ie. non-existant servers), a common element of these attacks used to mask an attacker’s identity. By doing a simple check to ensure that the server is real, all XML-RPC requests will have to originate from properly configured servers. For example, hackers will often use spoofed Reverse DNS entries (fake servers) when trying to brute-force your login passwords using the system.multicall function in XML-RPC (aka brute force amplification attacks). The plugin also employs a number of other methods to block these types of attacks. Stopping these attacks improves the security of your site.

released 06/04/16

  • Made various code enhancements and improvements.
  • Made various performance and speed optimization improvements.
  • Added an early-firing Pingback spam filter that STOPS pingback-based DDoS attacks. This filter fixes the security issue inherent to Pingbacks. It preempts WordPress’ slower Pingback validation with a very, very fast pre-check filter that eliminates 99.9% of pingback spam and saves a TON of bandwidth and server load. The plugin previously still blocked Pingback spam, but it fired after WordPress processed the Pingback. By adding the pre-check filter to the front of the stack in the processing queue, it prevents your site’s XML-RPC functionality from being abused for use in Pingback-based DDoS attacks against other sites, it prevents your site from being the victim of Pingback-based DDoS attacks, it takes a huge load off of WordPress by catching and blocking 99.9% of spam before processing, which speeds up your site and improves scalability.

  • Added an .htaccess file to the wp-spamshield directory to control browser access to certain files.
  • Added a fix to ensure that certain security plugins could not inadvertently block browser access to the jscripts.php file. This fix will prevent most of the occurrences of the issue discussed in Troubleshooting Guide step 14.
  • Upgraded the .htaccess file in the data directory (that protects the log file) to be compatible with changes in Apache 2.4.
  • Modified the log file creation process so that WordFence (and any other security plugins that compare plugin files against the WordPress repository) will no longer give the following warning: “Modified plugin file: wp-content/plugins/wp-spamshield/data/temp-comments-log.txt” when Blocked Comment Logging Mode is turned on. This file is supposed to change, since it’s the log file.

1.8.2

released 03/16/15

  • Increased minimum required WordPress version to 3.8 and added a minimum required PHP version of 5.3, as we are no longer supporting PHP 5.2. The PHP team stopped supporting PHP 5.2 back in 2011, and even PHP 5.3 reached its end of life in August 2014. WordPress has a current minimum requirement of 5.2.4, but PHP 5.4 is recommended – see the WordPress requirements. It’s extremely important that users stay up to date with the most recent version of WordPress (currently 4.1.1) and a reasonably up-to-date version of PHP for security, functionality, and website performance. (Not only are the newer versions more secure, but they are faster, so its a double win.) We recommend PHP 5.4 or higher. Also, see PHP Unsupported Branches for more info.
  • Fixed XHTML validation error in the hidden input fields on the forms.
  • Internationalized the formatting of numbers used throughout the plugin so users in different countries will see numbers formatted according to their local customs. This will show in the blocked spam stats on the dashboard, spam counter widgets, and in the blocked comments log.
  • Updated the antispam filters.

This feature was rolled back while we look into the compatibility issues.

  • Updated the antispam filters.
