11 Best AntiSpam Plugins for WordPress!

Plugin AntiSpam

Did you start a blog a few months ago and now it’s getting both a lot of traffic and a lot of comments? Have you created a contact form where you should receive important messages, but only receive Spam?

All this can be solved using some plugins from the list. We have selected 10 plugins and placed them in order of importance.

I recommend that you download a maximum of 2 plugins, no more. Because they could slow down the site excessively for the user. I’ll give you an example: WordFence is probably the most powerful plugin on the list, but we download and use it at certain times.

On WordPress it says that over 3 million users use it. Which is positive news on the one hand, but on the other hand it means that 3 million users slow down the site when they could activate once a week.

Why use WordPress AntiSpam Plugins?

Plugin AntiSpam WordPress

They increase SEO: when Google ranks your site, it checks internal links, comments and even the text (plus lots of other things, I want to focus on the comments though). If you see poor quality comments that might bother certain types of users, try to penalize the site and put those spam-free clean sites first.

Time saving: If you want to write the best articles on the market, you will need a lot of time. You can’t take care of both comments and articles. Spam plugins will make sure you have to take a look at the day and the end (just to see if everything works perfectly).

Improve the loading speed : unless you use the Lazy Load of comments, every time a user enters the site he will have to load both the comment text (which weighs little) but also the avatar (user image). Which weighs an average of at least 10 KB.

Multiply 10 KB by 50 comments, it’s almost half a mega (minimum as we said) and above all it’s 50 requests to the server. In short, you can slow down the site by 2-5 seconds.

Maintaining Website Reputation: As we mentioned earlier, some sites prefer to remove comments as long as they don’t lose reputation, but that doesn’t allow them to grow further on Google. The solution is to use AntiSpam plugins.

After all this long introduction, let’s start talking about the best WordPress Antispam plugins 2020.

Akismet

Akismet

It’s impossible not to know Akismet if you’ve been using WordPress for a while. It’s an antispam plugin developed by Automattic (that’s right, the ones who developed WordPress).

Akismet is one of the most popular plugins on the market in fact it has over 5 million active installs.

Since most of the spam comes from comments, Akismet monitors the comment section of your website very accurately. Automatically checks all comments and separates comments that may be suspected of being spam from useful comments which are immediately posted.

It is very easy to set up. In fact, just go to the Akismet site , register and then they will offer you API keys. These will need to be added inside the Akismet WordPress plugin. 

Unique features :

  • Easy to use
  • Compatible with major WordPress plugins
  • Advanced comment filter
  • Very powerful
  • Provides the API key for websites

Best for: WooCommerce and Blogs that get a lot of comments

Price : Free, Pro version starts at $ 5.

Antispam Bee

Antispam Bee

If you want an antispam plugin that does its job immediately without any user registration, AntiSpam Bee may be your best choice. It is a completely free plugin, and no matter what type of website you use, it will help you eliminate spam. 

AntiSpam Bee has many features to create a safe website for you. It can block comments from IP addresses, languages, and even countries to prevent spam from entering your website. You will also receive by email every day how many spam comments have been blocked.

Additionally, you can also add an approval limit to comments and pings. It will automatically delete other types of comments. If you wish, you can also exclude trackbacks and pingbacks from spam detection. 

Another really useful function is the one that goes to see in some databases if an IP address has been marked as spam. If so, the user’s comment will be blocked until we give consent.

Unique features:

  • Consider the comment time
  • Allow comments in a certain language
  • Block comments from some countries

Wordfence

Wordfence

Wordfence is the most used plugin on the list after Akismet. Over 3 million downloads. It is updated monthly in the WordPress dashboard, but its codes are changed much more frequently.

In fact this plugin is the most complete on the list. No, really! There is no comparison. Block users, bots, block everything you can think of. However, all this has a flaw, the speed of the site.

I realized that the plugin weighs down the site while being compatible with cache plugins. The advice I can give you that I give to my customers is to install it once a week to do some checks.

In fact, it allows you to check if there is any virus on the site, if something works wrong, it is a perfect plugin for protection against spam, malicious traffic, Brute Force attacks. It will carefully check your website by scanning the contents of your files, posts and comments.

Unique features:

  • Two-factor authentication (2FA)
  • CAPTCHA prevents bots from logging in
  • Disable or add 2FA to XML-RPC

CloudFlare

CloudFlare

Cloudflare is not actually a plugin, but a free service (it also has a paid version but you won’t need it).

I leave you this article so you can learn more. But what you should be interested in knowing is that it acts as a content distribution network.

Yes, I know it’s unclear and so I’ll try to use simpler language. In short, if you have hosting, you will have servers. These servers are located in some countries, ours is in Germany. A user who wants to see our site will have to make a request to Germany.

This is very bad for users who live perhaps in the United States. Cloudflare will offer you over 200 servers. Do you think they have 2 servers in Italy, in Milan and in Rome. All of this could speed up the site.

For most people it is the best choice. However, we use it on client sites but not ours because it was developed to be very fast and because we would like to transfer to Kinsta . They have a proprietary CDN that works differently than Cloudflare but we like it more in turn.

But what you should be interested in is that Cloudflare blocks all types of spam from bots, since the traffic will go through their server, they will be able to recognize spam from real users.

Unique features:

  • Protection from DDoS attacks
  • CDN
  • Advanced Web Application Firewall (WAF) Security
  • Image optimization
  • Automatic optimization for mobile devices
  • Uptime del 100%
  • SSL certificate

Ideal for: speeding up and blocking bots

Blackhole for Bad Bots

Blackhole for Bad Bots

We finally got to this plugin. Creation is a genius. As the name implies, Blackhole for Bad bot is a virtual trap for malicious bots (spammers). Bots have been known to use server resources excessively and act maliciously on your website.

Blackhole for Badbots is a plugin that through algorithms discovers whether it is a person or a bot, if so, it will take it into a trap (black hole) so that the bot can never return to the site.

To make the plugin work, you need to add a little code to the Page Footer (there are many plugins that allow you to do this). Then you need to add a code in the Robots.txt file.

Let’s say it takes longer than other plugins to add, but it’s worth it. Fully works with WordPress APIs and other security plugins. The plugin is updated regularly. 

You can have an email sent to you every time a bot is trapped. From the settings you can whitelist IP addresses. The developer has also added a feature that allows you to show the bot a personalized message.

By default, it doesn’t block search engine bots like Google Bot or bing.

Unique features:

  • 100% block bots
  • Updated regularly
  • Friendly GDPR

Zero Spam

Zero Spam

I am happy that in recent years many developers have stopped using CAPTCHA. Because it is true that it allowed to decrease spam comments and many other things. But on the other hand, however, it made users want to comment.

Zero spam is a plugin that does not use the CAPTCHA. All you need to do is install the plugin on your WordPress site and in seconds you will have everything done.

It uses an innovative method to block spam, essentially client and server side JavaScript key validation to prevent bots from leaving spam comments. Basically, users can’t comment without JavaScript enabled.

Like many plugins on this list, it allows you to block IP addresses, then allows you to block users from certain countries. It does similar things to so many other plugins.

Some tricks to avoid spam

A few years ago the famous billionaire and philanthropist Bill Gates said that within 2 years all the spam circulating on the web would be over. If you are reading this article, it means that spam is by no means gone. Sin.

But it is also true that technology has evolved and now stopping spam is much easier as we have seen.

Let’s see some tricks to avoid spam:

  • Using good hosting, we always recommend Kinsta to everyone because they have developed anti-spam software similar to CloudFlare (the level is not the same, but for over 85% of people it will be fine)
  • Always update WordPress because plugin code errors or outdated themes are often used
  • Block IP addresses that have left spam in comments or contact forms
  • Never open links left in comments by spammers, as they may steal your WordPress site data 
  • Create a list of blacklist words, if you go to WordPress, settings and finally comments, from there you can put all forbidden words

Conclusion

As an owner of multiple WordPress sites, I think the choice of the antispam plugin for WordPress depends on the characteristics of the traffic you are receiving.

We also showed you that each plugin is ideal for different sites. In any case, I recommend that you use CloudFlare together with Akismet . Trust me it will block all spam.

For those who realize that it is not enough because maybe it receives many visits. Then he will have to check if he receives more spam from Bots or Users.

In case of bots then the best choice is the Blackhole for Bad Bots plugin , in case of your competitors then Stop Spammers could be the best choice.

I hope this tutorial was useful to you, in case you have any doubts, write in the comments and we will help you!
