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 Since your users won’t be inconvenienced by outdated and frustrating anti-spam methods, you will provide a smoother, trouble-free experience for your website users, which leads to improved readership, ad revenue,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.

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. WP-SpamShield complies with even the strictest European Data Protection and Privacy Laws, and is 100% GDPR compliant. For more info, see this FAQ.

Minimum Requirements

  • WordPress 4.0+ (Recommended: WordPress 4.5 or higher)
  • PHP 5.3+ (Recommended: PHP 5.6 or higher) [PHP 7 Compatible: YES – 100%]
  • Your server must be configured to allow the use of an .htaccess file. The vast majority of users will have no issue here, because most web hosts allow this by default. However, if yours does not, you will need to contact them and ask them to enable it on your site. If they won’t, then it’s time to get a better web host. WordPress loses a lot of functionality if you don’t have use of .htaccess enabled, so this is important for full functionality of WordPress and other plugins as well.) Note: By definition, a standalone Nginx server would not meet this requirement, but an Apache/Nginx hybrid setup would. (Nginx is setup as a reverse-proxy in front of Apache. This type of setup offers high-performance and is recommended.)

Please see the plugin documentation’s minimum requirements section for more information.

To find web hosts that meet and exceed the requirements, see our list of recommended web hosts.

WordPress Security and Software Piracy Warning

WP-SpamShield is a premium WordPress anti-spam plugin. This software requires a paid license to use, and it can only be legally acquired by purchasing it from CodeCanyon.net, at this URL: https://codecanyon.net/item/wpspamshield/21067720. If you have downloaded it from any other website, then your copy is not legitimate and is not safe to use.

Sometimes people try to get premium WordPress plugins for free (or at extreme discounts), by downloading them from “warez”, “nulled”, or “discounted” plugin sites. These are not legitimate copies, and this is software piracy. Using software from these sites is extremely dangerous for your website’s security, and it is illegal. These warez/nulled/discount websites provide a dangerous hacked version of the plugin that includes malware code and backdoors that will allow hackers to compromise the security of your website. These websites try to claim that what they doing is legal, and that they are only distributing software under the GPL license. This is absolutely false, but unfortunately people fall victim to this scam. One variation of these sites offers extremely discounted “licenses” for the plugin. These are fraudulent “licenses”, and these copies are just as dangerous as the “free” ones. These are just another type of warez/nulled site, but they may seem slightly more legitimate because you have to pay something.

Please keep in mind that using pirated software is theft and it hurts the plugin developers, which makes it more difficult and expensive to provide high-quality software. This ends up hurting everyone. While it may seem like you are getting something for free and that no one is getting hurt, using pirated software has a high cost, for everyone. Just don’t do it.

If you want to get the WP-SpamShield plugin for free, consider joining our Affiliate Program. If you refer even 4 people, you have effectively gotten the plugin for free, and are already making a profit. That is a much better option than using a pirated/hacked copy of the plugin, and it helps everyone. Not only do you get the plugin for free, but you make money as well. No “free” plugin can offer you that. Win-win!

If you find this information on any website other than CodeCanyon.net, then this content has been illegally copied, and you are likely visiting a software piracy website. To get a legal (and safe) copy of the plugin, buy WP-SpamShield from CodeCanyon, or visit WP-SpamShield’s documentation and homepage at Red Sand Media Group’s website.
