CleanTalk works faster than most of the other anti-spam plugins. It is common knowledge that the faster your site loads, the better your customer experience is, the better your SEO will be, and the better your site will convert. Speed is becoming increasingly important in SEO, conversion and user experience. Today, site speed is one of the most important ranking factors on Google.

Существуют различные способы повышения эффективности загрузки вашего сайта и важный параметр для эффективности это установка хорошо развитых плагинов от авторитетного источника.

Среди анти-спам плагинов, CleanTalk является одним из самых быстрых. Несмотря на большую функциональность плагина, разработчики оптимизируют производительность плагина так, что CleanTalk быстрее чем многие аналоги. Этому способствует облачная архитектура сервиса, так как все расчеты производятся в облаке, а не на сервере, сервер получает готовый результат для дальнейших действий.

https://s.w.org/plugins/cleantalk-spam-protect/screenshot-5.png?r=1288723

Как работает CleanTalk

  • Посетитель пишет комментарий или регистрируется.
  • Плагин CleanTalk отправляет параметры действий в облачный сервис CleanTalk.
  • Сервис анализирует полученные параметры.
  • Если это посетитель, то комментарий публикуется. Если это спам бот, то CleanTalk блокирует этот комментарий или регистрацию.
  • Параметры записываются в журнал, который можно посмотреть в Панели управления сервисом.

CleanTalk разрабатывает облачный сервис защиты от спама в течении 5 лет и создала действительно надежный анти-спам сервис предназначенный для вас, чтобы гарантировать вашу безопасность.

Журнал спам атак

Сервис CleanTalk (плагин является клиентским приложением для CleanTalk анти-спам сервиса) записывает все отфильтрованные комментарии, регистрации и другие спам атаки в «Журнал спам атак» и хранит данные 45 дней. Используя журнал, вы можете обеспечить надежную защиту вашего веб сайта без ложной/положительной фильтрации.

SpamFireWall

CleanTalk has an advanced option «SpamFireWall». This option allows blocking the most active spam bots before they get access to your website. It prevents
spam bots from loading website pages so your web server doesn’t have to perform all scripts on these pages. Also it prevents scanning of pages of the
website by spam bots. Therefore SpamFireWall significantly reduces the load on your web server.
SpamFireWall also makes CleanTalk the two-step protection from spam bots.
SpamFireWall is the first step and it blocks the most active spam bots.
CleanTalk Anti-Spam is the second step and checks all other requests on the website in the moment of submitting comments/registers etc.

How SpamFireWall works?

  • Посетитель входит на ваш веб сайт.
  • HTTP request data are being checked in the nearly 5.8 million of the identified spam bot IPs.
  • Если это активный спам бот, он получает пустую страницу, если это посетитель, то он получает страницу сайта. Это совершенно прозрачно для посетителей.

Вся деятельность CleanTalk Спам FireWall регистрируется, в процессе фильтрации.

SpamFireWall DDoS Protection

Spam FireWall может смягчить HTTP/HTTPS DDoS атаки. Когда злоумышленник делает GET запросы для атаки на ваш веб сайт. Spam FireWall блокирует все запросы с плохих IP адресов. Ваш веб сайт выдает нарушителю специальную страницу с описанием отказа вместо страниц сайта. Поэтому Spam FireWall может помочь снизить нагрузку CPU вашего сервера.

Защита от XML-RPC перебора

Spam FireWall может снизить XML-RPC брутфорс атаки с плохих IP адресов. Это может помочь предотвратить брутфорс атаки удаленного вызова процедур.

How to protect sites from spam bots without CAPTCHA?

Самым распространенным методом является CAPTCHA-это раздражающая картинка с кривыми , косыми символами, которые и предлагается ввести посетителю. Предполагается, что спам боты не смогут распознать эти символы, а посетитель сможет. Для посетителя капча вызывает огромное раздражение, но если хочется высказаться, то приходится раз за разом вводить символы, ошибаясь и начиная заново.
Иногда CAPTCHA напоминает каракули 2х летнего ребенка. Для пользователей с проблемами зрения, расшифровка становится непреодолимым препятствием. CAPTCHA для людей означает «ненанвисть». Плохо читаемая CAPTCHA останавливает около 80% посетителей сайта. После двух неудачных попыток ввести капчу, до 95% посетителей прекращают дальнейшие попытки.
При виде капчи и ошибок ввода, многие посетители покидают ресурс. Таким образом CAPTCHA помогает защитить ресурс от ботов и посетителей. CAPTCHA это не панацея от спама. Есть сомнения относительно необходимости CAPTCHA?

В конечном счете Капчи бесполезны для спама потому что они предназначены что бы сказать вам ‘Человек это или нет, но не скажет, является ли это спамом или нет’ Matt Mullenweg

Вы можете не работать в IT что бы знать что такое спам. Кроме куч нежелательной почты, есть специальные спам боты или специальные компьютерные программы, что бы действовать как человек на веб сайте что бы размещать нежелательные сообщения в интернете для рекламы сомнительных услуг, несмотря на то что часто спам сообщения даже не имеет смысла. Аналогично бактерии и вирусы развивают устойчивость к антибиотикам в реальном мире, спам боты становятся более устойчивыми, проникая через интернет firewall’ы и этапы безопасности.

CleanTalk особенности

CleanTalk антиспам один из самых быстрых плагинов который позволяет снизить нагрузку на сервер. Один из важных параметров для каждого веб мастера является скорость сайта, поэтому мы уверены что наш плагин потребляет меньше ресурсов насколько это возможно. Облачный сервис обеспечивает преимущество, потому что все проверки происходят в облаке.

CleanTalk team has developed unique anti spam algorithms to assess visitors’
behavior. CleanTalk analyzes user behavior and the parameters of the filled
forms. Our anti-spam module, being installed in your website, sends the
behavior parameters of either a visitor or a spam bot. When these parameters
are estimated, the anti spam service makes a decision – to post a message or to define it as spam and reject it. Based on these checks, the service forms its own list of email addresses used by spam bots.

The registrations of visitors are being checked in a similar manner. The service adds to the blacklist not just email addresses, but also IP addresses and domains of websites that promote themselves through spam mailing. All of this happens automatically and requires no action from the administration of the website. In 2.5 million queries the service makes a mistake in 40-45 cases, i.e. CleanTalk detects spam with 99.9982% accuracy. We constantly monitor these errors and make adjustments to our algorithms. Even with this exceptional accuracy our team is aiming to improve the figures over time.

Все в одном. CleanTalk защищает все формы сразу — комментарии, регистрации, обратную связь, контакты. Нет необходимости устанавливать дополнительные плагины для каждой формы. Вы сохраняете ресурсы и повышаете производительность вашего сайта.

Журнал спам атак. CleanTalk ведет запись всех обработанных комментариев, регистраций и любых спам атак в «Журнале спам атак» и хранит данные в журнале до 45 дней. Использую журнал вы можете обеспечить надежную защиту вашего сайта от спама и не иметь ложных/положительных срабатываний.

С помощью CleanTalk анти-спам вы можете проверить существующие комментарии и регистрации, найти и быстро удалить сразу все спам комментарии. Это позволяет администраторам веб сайтов автоматически проверить и определить спам ботов, комментарии и регистрации, которые не были определены с помощью обычных анти спам средств. Проверка существующих комментариев и пользователей проводится на основе почти 2 миллионов спам ботов. Подробная статистика позволяет пользователям CleanTalk контролировать весь процесс.

CleanTalk имеет дополнительную опцию «Spam FireWall», эта опция позволяет блокировать наиболее активных спам ботов прежде чем они получать доступ к веб сайту. Это предотвращает загрузку страниц на веб сайте спам ботами, поэтому веб серверу не нужно выполнять выполнять все скрипты на этих страницах. Так же он предотвращает сканирование веб сайта спам ботами. Таким образом Spam FireWall может существенно снизить нагрузку на ваш веб сервер. Spam FireWall может смягчить HTTP/HTTPS DDoS атаки. Когда злоумышленник делает GET запросы для атаки вашего сайта. Spam FireWall блокирует все запросы с плохих IP адресов. Ваш веб сайт выдаст нарушителю специальную страницу с описанием отказа вместо страниц сайта. Таким образом Spam FireWall может помочь вам снизить нагрузку на CPU вашего сервера.

Почему они спамят меня?

Спамеры хотят получить обратные ссылки с вашего веб сайта что бы улучшить PageRank своего сайта или перенаправить посетителей на вредоносный сайт. Спам может повредить вашей репутации у читателей и комментаторов, если вы не решите его. Это не редкость для некоторых WordPress веб сайтов получать сотни и даже тысячи спам комментариев в неделю. Тем не менее с помощью плагина CleanTalk, спамом можно легко управлять на вашем WordPress веб сайте.

Is the anti-spam protection safe for mobile visitors?

Yes, it is. The plugin doesn’t block mobile visitors as well as desktop website visitors. It uses several independent anti-spam tests to decrease the number of false outcomes and to have as low false-positive rate as possible. Multiple anti-spam tests help to avoid false/positive blocks for real website visitors even if one of the tests failed.

What does the plugin do with spam comments?

Spam comments are being moved to SPAM folder by default or you can set the option to ban spam comments silently.

How can I test the anti-spam protection?

Please use the email stop_email@example.com for comments, contacts or signups to see how the anti-spam protection works. Also you can see the logs for the last 7 days at the Control panel or look at the folder «Spam» for banned comments.

Is the plugin effective against spam bots?

The plugin Anti-Spam by CleanTalk stops up to 99.998% of spam comments, spam signups (registrations), spam contact emails, spam subscriptions, spam bookings or spam orders.

Does the plugin protect from brute force, DoS attacks and spam attacks?

Yes, it does. Please turn the option ‘SpamFireWall’ on in the plugin settings to protect your website from DoS/DDoS, XML-RPC attacks.

How does the plugin stop spam?

Please, note — administrator’s actions are NOT being checked.

The plugin uses several simple tests to stop spammers:

  1. JavaScript anti-spam test. 99% of spam bots don’t have full JavaScript functions support. So, the plugin has the code which can be run by normal visitor and can’t be run by the spam bot.
  2. Email, IP, domain spam activity list entries check. The plugin uses spam activity database online at cleantalk.org, consisting of more than 20 billion spam activity records of IPs, Emails, Domains and ASN. If the sender’s IP or Email is in the database, the sender gets some spam scores. To reduce false/positive rate the plugin not only uses the blacklist test to ban spammers, the sender will be banned when and only when multiple spam tests have been failed.
  3. Comment submit time. Spam bots usually submit the info immediately after the page has been loaded, this happens because spam bots don’t actually fill the web form, they just send $_POST data to the blog. The normal visitor sends the data after several seconds or minutes.
Will the anti-spam plugin protect my theme?

Yes, it will. The Anti-spam by CleanTalk is compatible with any WordPress theme.

What about pingback, trackback spam?

The plugin passes pingbacks without any checks by default. All trackbacks will be blocked if the sender had spam activity.

Can I use CleanTalk with Akismet?

Sure, you can use CleanTalk with Akismet. In this case you will probably have higher false/positive rate (when legitimate comments/signups are being denied), but you will have stronger anti-spam protection on your website.

Is CleanTalk better than Akismet?

Please look at this features comparison here https://cleantalk.org/cleantalk-vs-akismet

Can I use CleanTalk to remove pending spam comments?

Yes, you can. The plugin has the option to test all pending comments via database of spam active IP/Email, found spam comments will be moved to Trash folder.

How does the plugin find spam in pending comments or registered accounts?

The plugin checks all non-spam comments in the blacklist database and shows you those senders who have spam activity on other websites.
There are some differences between blacklist database and API to protect you from spam bot registrations/comments online. Blacklists show all history of spam activity, but our API (which is used in spam tests) relies on other parameters too: last day of activity, number of spam attacks during the last days etc. These mechanisms help us to reduce the number of false outcomes. So, there is nothing strange, if some emails/IPs are not found by bulk comments/accounts test.

To check comments please go here:

WordPress console -> Comments -> Find spam comments

To check users please go here:

WordPress console -> Users -> Find spam users

Should I use other anti-spam tools (Captcha, reCaptcha and etc.)?

CleanTalk stops up to 99.998% of spam bots, so you can disable other anti-spam plugins (especially CAPTCHA-type anti-spam plugins). In some cases several anti-spam plugins could conflict with each other, so it would be better to use just one plugin.

Is the plugin compatible with WordPress MultiUser (WPMU or WordPress network)?

Yes, the plugin is compatible with WordPress MultiUser. Each blog in multisite environment has individual anti-spam options for the protection from spam bots.

After the installation I noticed that the number of spam attacks has been increased in the stats

There are a few reasons for this:

  • With the indexing of your web-site by the search systems, appearance of external links and better search results position, your web-site attracts more and more spambots.
  • Non-transparent protection systems like CAPTCHA or question/answer, that don’t have spam attacks stats, don’t let you see the whole picture, or the picture is incomplete.
  • Counting methods for spam attacks and spam bots are different for different systems, thus the diversity appears. We seek to provide detailed stats.
Why my dummy «spam» comment passed to the WordPress?

The plugin has several options to detect spam bots and humans. If you just post spammy text like this:

"I want to sell something", "Buy something here.." and etc

the comments will be passed, because the plugin detects sender as a human. So, use special email stop_email@example.com to test the anti-spam functionality or wait a few days to see how the plugin works.

Is it free or paid?

The plugin is free. But the plugin uses CleanTalk cloud service to filter spam bots. You have to register an account and then you will receive a free trial to test anti-spam for comments, registrations, bookings, contacts or orders. When the trial (on CleanTalk account) is finished, you can renew the subscription for 1 year or deactivate anti-spam plugin.

Can I use CleanTalk with cache plugins?

Anti-spam by CleanTalk doesn’t use static HTML code in its templates, so all anti-spam functions work correctly with any WordPress cache plugins.

Does the plugin protect from spam bots if I use forms with third-party services?

Yes, it does. Plugin protects web-forms on your websites which send data to third-party servers (like MailChimp). To enable this protection set the option ‘Protect external forms’ in the plugin settings.

Does CleanTalk compatible with Cloudflare?

CleanTalk is fully compatible with CloudFlare. Service doesn’t filter CloudFlares IP’s (AS13335) through blacklists database, so in this case plugin/service filters spam bots using other anti-spam tests.

Is CleanTalk compatible with a content delivery network (CDN)?

Yes, it is. CleanTalk works with any CDN system, i.e. CloudFlare, MaxCDN, Akamai.

Can I use CleanTalk functionality in my plugins?

Yes, you can. Just use following snippet:

<?php 
if(!function_exists('ct_test_message')){
    include_once( ABSPATH . '/wp-content/plugins/cleantalk-spam-protect/cleantalk.php' );
}   
//for registration test:
$res=ct_test_registration("nickname", "stop_email@example.com", "127.0.0.1");
//or for some other messages (contact forms, comments etc.)
$res=ct_test_message("nickname", "stop_email@example.com", "127.0.0.1", "test message");

$res now contents array with two parameters:
* $res[‘allow’] — is request allowed (1) or not (0)
* $res[‘comment’] — comment for our server’s decision.

I see two loads of script cleantalk_nocache.js. Why do you use it twice?

This script is used for AJAX JavaScript checking. Different themes use different mechanisms of loading, so we use two methods for loading our script. If you absolutely know what you are doing, you can switch one of the methods off by defining constants in your wp-config.php file:

define('CLEANTALK_AJAX_USE_BUFFER', false); //false - don't use output buffering to include AJAX script, true - use it

или

define('CLEANTALK_AJAX_USE_FOOTER_HEADER', false); //false - don't use wp_footer() and wp_header() for including AJAX script, true - use it
Can I add exclusions for some pages of my site?

Yes, you can. Add this string in your wp-config.php file before defining database constants:

$cleantalk_url_exclusions = array('url1', 'url2', 'url3');

Now, all pages containing strings ‘url1’, ‘url2’, or ‘url3’ will be excluded from anti-spam checking. Remember, that this option will not be applied in registration and comment checking — they are always protected from spam. This is similar to regular expression /.url1./ or wildcard like url1.

For example: You need to except these URLs.

example.com/some/thing
example.com/some/one
example.com/some/body

You need to type this:

$cleantalk_url_exclusions = array('some');
Can I not send my personal data to CleanTalk servers?

Yes, you can exclude your data. Add this string in your wp-config.php file before defining database constants:

$cleantalk_key_exclusions = Array('key1', 'key2', 'key3'); 

Now all fields in your submissions with the keys named ‘key1’, ‘key2’ or ‘key3’ will be excluded from spam checking.

How to test SpamFireWall?

Use special IP 10.10.10.10 in URL to test SpamFireWall. For example,

https://cleantalk.org/blog/?sfw_test_ip=10.10.10.10
How can I enter access key in WPMU version?

To set up global CleanTalk access key for all websites in WPMU, define constant in your wp-config.php file before defining database constants:

define('CLEANTALK_ACCESS_KEY', 'place your key here');

Now, all subsites will have this access key.

Why is CleanTalk faster and more reliable than stand-alone solutions?

All anti-spam checks are held in the cloud and don’t overload the web server. The cloud solutions have a huge advantage since the parameters are being compared with information from more than 100,000 websites.

I see a lot of blocked messages with the reason «Forbidden. Please enable JavaScript. Spam sender name.» in my logs

A lot of spam bots can’t perform JavaScript code, so it is one of the important checks and most of the spam bots will be blocked with the reason «Forbidden. Please enable JavaScript. Spam sender name.» All browsers can perform JS code, so real visitors won’t be blocked.

If you or some of your visitors have the error «Forbidden. Enable JavaScript.» please check JavaScript support in your browser and do this JavaScript test at this page: https://cleantalk.org/checkout-javascript-support.

If you think that there is something wrong in the messages blocking, let us know about it. Please submit a support request here: https://cleantalk.org/my/support.

Does the plugin work with Varnish?

CleanTalk works with Varnish, it protects WordPress against spam, but by default the plugin generates a few cookies for the protection from spam bots and it also disables Varnish cache on pages where CleanTalk’s cookies have been stored. To get rid of the issue with cache turn off the option ‘Set cookies’ in the plugin settings.

WordPress console -> Settings -> CleanTalk -> Advanced settings

Now the plugin will protect WordPress comments, registrations and most of popular contact forms, but will not protect some of rarely used contact forms.

Does the anti-spam plugin work with Accelerated Mobile Pages (AMP)?

Yes, it does. But you have to turn off the option ‘Use AJAX for JavaScript check’ in Advanced settigns of the plugin to be fully compatible with Accelerated Mobile Pages.

How to close renewal or trial notice in the WordPress backend?

To close the notice please save the plugin settings again or it will be closed automatically within 60 minutes after the renewal.

I’m using PHP 4.2 version and i’m getting errors related with JSON. Why does it happens?

СleanTalk is no longer supports PHP lower than 5.2 version because the support code have incompatibility with PHP 7 version. Please, upgrade your PHP. If you couldn’t perform that, let us know about it via support ticket here: https://cleantalk.org/my/support.

Should I change anything in the plugin’s settings or in my CleanTalk Control Panel when I switch my website from HTTP to HTTPS or vice versa?

No. You don’t need to change anything in the plugin’s settings or in your CleanTalk Control Panel. The plugin will work regardless of the protocol.

How to use Anti-Spam Log?

— Time period for all spam records you want to see.

— Filter spam records by their status: Any status, Denied, Approved.

Spam Comment Management

By default, all spam comments are placed in the spam folder, now you can change the way the plugin deals with spam comments:

  1. Move to the Spam folder. All spam comments will be placed to the folder «Spam» in the WordPress Comments section except comments with Stop-Words. Stop-Word comments will be always stored in the «Pending» folder.

You can prevent the proliferation of Spam folder. It can be cleaned automatically using the option «Keep spam comments for 15 days.» Enable this option in the settings of the plugin: WordPress Admin Page —> Settings —> Antispam by CleanTalk —> Advanced settings —> enable «Keep spam comments for 15 days» —> Save Changes.

  1. Move to Trash. All spam comments will be placed to the folder «Trash» in the WordPress Comments section except comments with Stop-Words. Stop-Word comments will be always stored in the «Pending» folder.

  2. Ban comments without moving to WordPress backend. All spam comments will be deleted permanently without going to the WordPress backend except comments with Stop-Words. Stop-Word comments will be always stored in the «Pending» folder.

What comments were blocked and banned can be seen in the Anti-Spam Log here: https://cleantalk.org/my/show_requests?int=week

To manage the actions with spam comments, go to the Control Panel, select the website you want to change the actions for and go to «Settings» under the name of the website.

Please, read more here:
https://cleantalk.org/help/spam-comment-management

Как я могу сообщить о пропущенном спаме или некорректной фильтрации?

If you think the service has missed a spam bot or improperly filtered visitor to the website, you may notify us via the Anti-spam control panel. To do this,
Log in to Control panel https://cleantalk.org/my.
Click the line «Log» under the name of your website.
When you mark a record as «SPAM», its e-mail and IP-address will be added to your personal blacklist for your website.

Godsend

Brilliant plugin and a godsend. It’s stopped some spam via my forms early on and no one has tried since to post cra*p.

The firewall component has been stopping regular attempts by the evil spammers and the detailed logs are very helpful to see what’s been going on behind the scenes.

Totally recommend it.

Clean Talk Antispam

Clean talk is very good value for money… if Carlsberg did plugins it would be Clean Talk 🙂 Antispam protection of this quality is essential for a website today!

Super!

Does what it says on the tin.

Stopped spam dead in it’s tracks

My blog website used to get 100s of spams messages per day… it was a hassle to delete them manually and took about 5-10 mins of my time every few days. I wasn’t expecting much from an anti-spam plugin but thought I would give this one a go.. and guess what, no more spam! It has identified every single spam message correctly so far, and has stopped nearly 2000 spam messages in the last 5 days. Brilliant! I also like the fact that I can get some stats about my spam, like which country originated it and so on. Can’t fault it so far… highly recommended!

Wonderful

I cannot say enough about this plugin… protects my website 100%

this is really good

i really enjoy it with this plugin. Its easy to use and friendly also strong spam blocker
i recommended
