Antispam Bee’s simple operating interface is one of its strengths. It enables the user to customize comment spam folders and configure necessary filters. Moreover, by activating the spam reason, the plugin’s user can receive more in-depth insight into spam that affects their site the most. It is limited to combating comment spam. 

The plugin incorporates a basic geo-blocking feature; however, we recommend caution while using it. It depends on IP addresses and is prone to being unreliable.

Pros

Price: Free version with a pro license that costs $73 a year

Verdict

Spam Master is compatible with most email clients, and can protect your site from most comment spam. However, as we installed the plugin, it told us that the firewall blocked a threat. Considering this is a test site with no traffic and blocked from crawlers of all kinds, this is hard to believe. It feels spurious to claim a success so early in the setup process.

Verdict

OOPSpam offers a unique selling point: enabling users to target and prevent spam based on particular languages and geographic locations.

Additionally, pricing based on API calls may be confusing to comprehend.

There is minimal provision for analytics, rendering it suitable for those desiring automated spam control. There are premium attributes equivalent to those offered by a typical security plugin; however, those features were not examined in the course of writing this article.

11. WP-SpamShield

WP-SpamShield implements double security measures to safeguard your site effectively. The primary layer is the Anti-Spam Layer. This section leverages JavaScript and cookies to distinguish between humans and spambots algorithmically. Spambots are incapable of passing through the Anti-Spam Layer.

Price:  Free

Verdict: WP-SpamShield engaged in a verbal argument with another plugin developer, alleging that their plugin was wrongfully blocked. The feud led to WP-SpamShield’s removal from the WordPress repository. Although this does not influence the plugin’s potential to stop spam, compatibility issues are expected to arise.

The plugin is akin to Akismet in that it employs sophisticated algorithms and filters that safeguard against spam. However, WP-SpamShield is more comprehensive and potent than Akismet.

There are other anti spam plugins, like Spam Destroyer, and some security plugins like WP Cerber Security that block WordPress spam comments as well.

Key decision factors in choosing the best anti spam plugin for WordPress?

When it comes to effective anti-spam protection, there are several must-have features that a plugin should have to protect your website from unwanted content and malicious activities, whether you are trying to stop a spam comment, a spam registration, or a spam submission from getting through.

• Review comments and forms for spam: The plugin should flag spam and allow you to manually review and moderate comments and form submissions.
• Automatically remove spam: You may also want a plugin that can automatically detect and remove spam comments, messages, or submissions without requiring manual intervention. A word of caution here: you need to be absolutely sure that only spam is weeded out. Some aggressive plugins may keep out legitimate user-submitted content.
• Spam bot protection: Set up a robust firewall that can analyze incoming traffic and block suspicious or spammy requests, preventing them from reaching your website. If your anti-spam plugin doesn’t have a firewall, install MalCare’s advanced firewall that blocks bots and attacks. 
• Require zero client interaction: This is a personal preference, and there are divided opinions on whether interaction is a good or bad UX practice. reCAPTCHA, for example, becomes an additional step in the customer’s process. It’s inconvenient. This is why invisible protection is sometimes considered a superior method. 
• Retrospective spam cleaning: Unless yours is a brand new site, you want a plugin that scans existing content as well. Deleting any comments or forms you may have missed or giving you a fresh start is always a boon. 

Do you need an anti-spam plugin for your WordPress site? 

While it is not an absolute requirement, having an anti-spam plugin for your WordPress site can greatly enhance your website’s security and user experience. 

1. Spam protection: A WordPress anti spam plugin provides dedicated features and filters to effectively detect and block spam comments, contact form spam submissions, and other malicious content. It helps keep your website’s content clean and free from unwanted or harmful content.
2. Resource-saving: You can automate the process of filtering out spam, reducing the time and effort required for manual moderation. This allows you to focus on more important tasks related to managing and growing your website.
3. Improved user experience: Spam comments and messages create a negative user experience for your visitors. By minimizing the presence of spam, you ensure that genuine user comments and messages receive the attention they deserve.
4. Additional security layers: Some anti-spam plugins offer additional security features such as bot protection, CAPTCHA integration, and IP blocking, which can help safeguard your website against spam and potential threats. Of course, none of these are adequate replacements for a good firewall, but they help.
5. Improved performance: Spam bots are an egregious waste of server resources. If your WordPress hosting bill is a little higher than it should be, bots could be the reason for the spike.

What are some other ways to prevent spam? 

A WordPress anti-spam plugin is the easiest way to combat spam, but there are other effective methods too. 

1. reCAPTCHA: Implementing reCAPTCHA or similar CAPTCHA systems can help distinguish between genuine human users and automated bots. It adds an extra layer of security by requiring users to complete a challenge to prove their authenticity.

2. Security plugin: A security plugin like MalCare will  protect your website from spam, malware, and all other threats. It offers features such as automated malware cleaner, malware scanner, and advanced firewall protection, giving you a robust security system for your WordPress site.
3. Geoblocking: Consider implementing geoblocking to restrict access to your website from specific regions or countries known for generating high volumes of spam. This can help minimize spam traffic and potential threats. However, also be warned that this is not a precise mechanism, and has been known to keep out legitimate traffic when implemented. 
4. Double opt-in forms: Implement double opt-in forms for newsletter subscriptions or user registrations. This process requires users to reconfirm their intent by clicking on a verification link sent to their provided email address, ensuring that only legitimate users are added to your email list or granted access to your site.

Instead of relying solely on one method, it’s often beneficial to combine multiple anti-spam strategies. Utilize a combination of techniques to create a comprehensive and layered approach to spam prevention.

Final thoughts 

To stop spammers on your website, leveraging the power of multiple tools and plugins can yield the best results. While CleanTalk stands out as the best WordPress anti spam plugin, your security systems can be further enhanced by pairing it with a robust security plugin like MalCare. MalCare offers a comprehensive suite of security features, including a top-notch scanner, one-click malware remover, and a reliable firewall. This synergistic approach ensures a strong defense against spam and malware, while enhancing the overall security of your website.
