Protecting comments from spam. WordPress protection plugins against comment spam

WordPress is an amazing solution for webmasters that allows you to get rid of many of the problems associated with developing a full-fledged website. One of these problems is spam protection, which is often extremely difficult to deal with.

1. Akismet

This is a standard anti-spam plugin for WordPress, which is installed along with the CMS. It was one of the first developed for WP, with almost the same team that worked on creating WordPress. It's about about Automattic, as many of you have already guessed.

Akismet checks every comment you add for spam links, which you can later manually disavow or approve. It is worth noting that the functionality of this plugin is limited solely to checking and labeling comments.

2. Antispam Bee

Antispam Bee is another WP plugin that allows you to evaluate the various components of each comment and stop any spam. The plugin provides the ability to confirm which commentators you can trust.

The plugin also checks IP addresses, Gravatar, etc. This allows you to stop almost any attempt to post spam comments.

3. Anti-spam

This anti-spam method is offered in two versions: free and one that costs $15. Free version focused on automatic operation, and you won't be able to make changes to the settings: just install the plugin and it starts working.

The paid version allows you to set up your own filters, that is, use lists of words, and also specify the maximum number of words for each comment.

In fact, it is one of the most effective anti-spam plugins for WordPress.

4. WP-SpamShield Anti-Spam

An all-in-one anti-spam solution for WordPress that not only fights spam comments, but also filters out trackbacks from suspicious sources, spam in feedback and even suspicious accounts during the registration process. This plugin does not implement CAPTCHA at all, and therefore does not affect the user experience in any way.

WP-SpamShield works great with plugins like Contact Form 7, Gravity Forms, Ninja Forms, JetPack Contact Forms & Comments, BuddyPress, bbPress, WooCommerce and will help you get rid of spam forever.

5.Advanced Invisible Anti-spam

Almost the most effective protection from WordPress spam, which can easily cope with spammers without using captcha. Despite its simplicity, it works great with advanced caching systems. This plugin offers filters that any webmaster can easily handle.

6. WP Anti Spam

This spam filter for WordPress checks comments, IP addresses, nicknames, email and specified sites for spam. You will be able to specify a minimum and maximum word count per comment, which will help you avoid annoying comments with just a link. The plugin also provides the ability to use a list of words that are prohibited from being used in comments.

7.BotPlug

This is one of many paid plugins that will cost you $12. Not only will it save you from spam, but it is also capable of fighting malicious bots and brute force attacks. With this plugin you can limit the number of requests to the server that originate from a specific IP address. If a bot tries to bypass this restriction, it will either be redirected to another page or encounter a CAPTCHA that verifies that the requests are made by a real person. In addition, you can block individual IP addresses that have been detected as spam.

8. AlphaOmega Captcha & Anti-Spam Filter

Another plugin whose purpose is to protect against spam in WordPress comments. It shows a captcha, which allows you to confirm that the comment is written by a real person, and here it is important to note that not every webmaster agrees to use spam filters without using a captcha.

The comment counting feature will help determine the effectiveness of the plugin, as you will see the number of blocked ones.

9. Anti-Spam by CleanTalk

This plugin does not use captcha or other security methods that require mechanical intervention from users. Such solutions are gaining popularity very quickly, since users are already quite tired of captchas.

The plugin counts blocked comments, attempts to send spam through the feedback form, as well as through the registration form on the site. It is compatible with the WooCommerce plugin, which means your online store is on WordPress based will also be protected from spam.

10. ZWS WordPress Anti Spam & URL Filter

This plugin for protecting your site from spam works in two ways: different ways. One is to eliminate the “website” field during registration, where spammers often enter spam links. The second way is that you will be able to use lists of banned words, which then serve as beacons for the plugin.

11. WPBruiser (no-Captcha anti-Spam)

Last but not least effective plugin also does not use captcha, but successfully protects comments, feedback forms, registration forms, etc. from spam.

It automatically blocks IP addresses found to be sending spam. In addition, your site will be protected from brute force attacks.

Translation of the article “ 13 Free WordPress Anti Spam Plugins to Prevent Comment Spam” was prepared by the friendly project team

Hi all. If you have a WordPress site, then you must be familiar with the problem of your site being flooded with spam comments. Of course, the Akismet plugin, which is installed there by default, does an excellent job of dealing with spam in WordPress, but the problem with this plugin is that it often marks completely human comments from real people as spam.

Until recently, I constantly checked my spam folder for comments that had been mistakenly placed there. Usually a day on my blog, about 50-70 comments. Eventually I got tired of it and started looking for a way to get rid of it. automatic spam Once and for all. And I found such a way :)

The idea of a captcha, which could improve the situation a little, did not suit me at all. I think that today you rarely see captcha on blogs; it is becoming a thing of the past, and rightly so. I once wrote that using a captcha on a blog scares off most commentators, and using a creepy digital captcha completely kills the desire to comment.

After some searching, I found an interesting and simple way to protect against spam, which is in replacing text fields, that’s what I want to talk about.

The essence of this method is that we create a new comment field with a new name, and hide the old field from the eyes of visitors. The spam bot, out of habit, will enter a comment in the standard field, since it is configured for this, but it will not be able to send this comment :) At the same time, regular visitors will enter comments into the form with a new name, and they will not even notice any changes.

So, let's move on to implementing this method. There are two ways for events to develop: either you old version engine, and your comments are displayed through html code, or you latest version, and comments are output via the function comment_form().

First option

Let's consider the option when comments are displayed through html code.

The first thing we need to do is find in the file comments.php, in the folder with the theme, a line responsible for displaying the field for entering a comment. Usually it looks like this:

This line should be replaced with the following construction:

The next step is to change the styles for these shapes. In order to hide the old form from the eyes of visitors, add to the file style.css:

Spamform (display: none;)

If your old comment form had styles attached, then you need to replace it in style.css All id="comment" on id="newcomment", then yours new form comments will look the same as before.

Well last step paste at the end of the file functions.php(before the sign ?> ) the following function:

//spam_detect add_filter("pre_comment_on_post", "verify_spam"); function verify_spam($commentdata) ( $spam_test_field = trim($_POST["comment"]); if( ! empty($spam_test_field)) wp_die("no-spam"); $comment_content = trim($_POST["newcomment"]); $_POST["comment"] = $comment_content; return $commentdata; ) //end

Second option

Now let's look at the second option, when comments are displayed using the function comment_form() .

Here the algorithm is almost the same as in previous paragraph. All we need to do is add two functions to the function.php file:

//Add a comment field add_filter("comment_form_defaults", "change_comment_form_defaults"); function change_comment_form_defaults($default) ( $commenter = wp_get_current_commenter(); $default["comment_notes_after"] .= "

"; return $default; ) //end //spam_detect add_filter("pre_comment_on_post", "verify_spam"); function verify_spam($commentdata) ( $spam_test_field = trim($_POST["comment"]); if( ! empty($spam_test_field)) wp_die("no-spam"); $comment_content = trim($_POST["newcomment"]); $_POST["comment"] = $comment_content; return $commentdata; ) //end

The first function adds a new comment field (similar to > in the previous paragraph), and the second function checks in which field the comment was entered. All that remains to be done is to close the old field from the eyes of visitors. To do this, paste it into the file style.css the following line:Comment-form-comment (display: none;)Again, in order for your new comment form to look like the old one, you need to style.css change everything id="comment" on id="newcomment". After I changed the fields, I haven’t had a single spam comment on my blog yet. I think that if there is any spammer who writes a comment manually, then Akismet will easily find him :) * * * Have you made a website, but don’t have time to support it?

Not included in this list Akismet, it is not free for commercial blogs. Many blogs are trying to make money, for this reason, this list includes only those plugins that are completely free. In addition, it filters too much. Often a lot of things end up in spam <a href="https://viws.ru/en/kakoi-rabotoi-na-domu-zanyatsya-domohozyaikam-rabota-dlya.html">good comments</a>, and on some blogs, these could be potential buyers who, without waiting for an answer, will leave and never return. I personally use a long-proven method To view the link you need to: Hello dear reader! Today we will talk about <a href="https://viws.ru/en/poleznyi-podpisatsya-na-kommentarii-k-soobshcheniyu-plagin-dlya-podpiski.html">wordpress comments</a>, about spam comments on blogs. I think you, like me, are already tired of constantly going to the “spam” folder and manually sorting through comments from automatic or, even worse, manual spam. Then look for a good, meaningful comment in this pile of rubbish, which was stuffed into the spam comments folder by mistake. That's right, I'm terribly tired of this too. At first I installed many different antispam plugins to protect WordPress from spam. But as practice has shown, all these actions are ineffective. Therefore, one very interesting solution was invented, although it was not invented by me! I borrowed this method from some blog. So, I decided to try it and implemented the hack on my blog. After three months, the flight was successful, not a single spam comment for three months. It’s hard to believe, of course, but it’s true. After the experiment, I came to the conclusion that my readers simply must know about protecting WordPress from spam comments using a useful hack - “field substitution”! <h2>The essence of the method!</h2> For manual spam, we will, as always, install a plugin Akismet. I think almost every blogger should have it. If it’s not worth it yet, then there is a lot of literature on the Internet about how to install it and how to activate it. This plugin will protect our blog from manual spam in comments. And the “field substitution” hack, in turn, will protect the blog from auto spam. I think it’s worth noting two big advantages of this dance with a tambourine: first, we get rid of <a href="https://viws.ru/en/myshka-ploho-rabotaet-na-stole-kak-ya-ispravil-problemu-s-postoyannym.html">constant problem</a> auto spam and secondly, you no longer have to edit engine files after updating WordPress. True, as always, there is a minus, you will have to cheat two files in our topic, comments.php And style.css. But in my opinion, this minus is insignificant. The essence of the method is approximately the following! If you are an advanced blogger, you should know that the standard comment field is named comment , so we will hide the real field and replace it with a new real-comment field. For your readers and visitors, everything will remain as before, but now they will fill in the visible real-comment field. But spam scripts will fill in the standard comment field, which we will hide. They don’t understand that a person will not be able to fill out a text field that is not visible on the blog pages. This is where we will catch a spam comment, because such a comment will be identified by the filled invisible comment field. In general, everything is as simple as two and two. A person fills out the visible real-comment field, and a spam script will fill out the standard comment field in the old fashioned way, but this time invisible. A filled invisible field will be a spam comment! :-) I think it's time to get down to business! <h3>1. Comments via the “comment_form()” function</h3> If you display comments using the comment_form() function (this function was introduced in WordPress 3.0 so that using a file functions.php, it was possible to completely replace the standard comment form). If your template uses exactly this function, then you need to open the file functions.php and add the following code there://Adding your own comment field add_filter("comment_form_defaults", "change_comment_form_defaults"); function change_comment_form_defaults($default) ( $commenter = wp_get_current_commenter(); $default["comment_notes_after"] .= " <label for="real-comment">A comment</label><textarea id="real-comment" aria-required="true" rows="8" cols="45" name="real-comment">

"; return $default; ) //END adding your own comment field
Now we hide our standard field comment, via file "style.css":
Comment-form-comment (display: none;)
So, we've completed the first part of the hack. Now we have a real-comment field that the visitor can see and fill in, and a standard comment field that is hidden! IN next step we need to determine which of these fields to skip and which to disable. If the visible field is filled, then we pass, and if the invisible field is filled, then we disable it. To do this, open the file functions.php and add the code there:
2. Comments not via the “comment_form()” function

If your comments are not displayed through the comment_form() function, like mine! In this case, open the file comments.php and find there the code that displays the field for entering a comment. Something similar to:

This code must be replaced with:

Now we need to hide the standard comment field. To do this, open your template's style file “style.css” and add the code there:
No-spam (position: absolute; left: -1000px;)
No-spam (display: none;)
Also in this method don't forget to add the code in the file functions.php, to determine which of these fields to skip and which to disable.
//Check for spam add_filter("pre_comment_on_post", "verify_spam"); function verify_spam($commentdata) ( $spam_test_field = trim($_POST["comment"]); if(!empty($spam_test_field)) wp_die("No spam!"); $comment_content = trim($_POST["real- comment"]); $_POST["comment"] = $comment_content; return $commentdata; ) //END spam check
That's basically it! Now spam comments will no longer disturb you and your blog. If you doubt whether you did everything correctly, you can check how this hack works to protect WordPress from spam. To do this, you need to remove from the file style.css changes made, refresh the blog page, fill out each comment field and try to post a comment!
