CleanTalk – Cloud-Based Anti-Spam Service to Keep Your Site Bot-Free.
NewsWatch Review.

Using CleanTalk on WPLift was a great test as we receive huge amounts of spam.
Oliver Dale,

I know you have heard of a number of anti-spam plugins. But you must know, the cloud-based ones are the best regarding detection rate. They compare all the content in forms with their own algorithm to find out the legibility.

The key selling point of CleanTalk for me is not simply its effectiveness. It’s the fact that CleanTalk works in the background. It does not make users jump through hoops in order to submit a comment or complete a form.

Free trial then $8 per year

Spam FireWall DDoS Protection

Spam FireWall can mitigate HTTP/HTTPS DDoS attacks. When an intruder makes GET requests to attack your website, Spam FireWall blocks all requests from bad IP addresses. Your website gives the intruder a special page with the description of DDoS rejection instead of the website pages. Therefore Spam FireWall helps to reduce CPU usage of your server.

Spam FireWall can mitigate XML-RPC brute force attacks. It blocks XML-RPC attacks from bad IP addresses. This helps to prevent bruteforce attacks by a Remote Procedure Call.

How to protect sites from spam bots without CAPTCHA?

The most popular anti spam method is CAPTCHA – the annoying picture with curved and sloping symbols, which are presented to the visitor to decipher and fill in. In is supposed that spam bots won’t discern these CAPTCHA, but a visitor will. CAPTCHA provokes great irritation, but if the visitor wants to comment, he has to fill in these symbols time after time, making mistakes and starting once again. Sometimes CAPTCHA reminds us of the doodles of a two year old child. For users with vision problems CAPTCHA is an insurmountable obstacle. Users hate captcha. Captcha for users means “hate”. Unreadable CAPTCHA stops about 80% of site visitors. After 2 failed attempts to decipher CAPTCHA 95% of visitors reject further attempts. At the sight of CAPTCHA and after input errors, many visitors leave the resource. Thus, CAPTCHA helps to protect the resource spam both from bots and visitors. CAPTCHA is not a panacea from spam. Doubts concerning the Need for CAPTCHA?

“Ultimately, CAPTCHAs are useless for spam because they’re designed to tell you if someone is ‘human’ or not, but not whether something is spam or not.” Matt Mullenweg

You do not have to work in IT to know what spam is. Besides piles of unwanted email, there are spam bots, or special software programs designed to act as human website visitors that post unwelcome messages over the Internet to advertise dubious services. More often than not spam messages do not even make sense. Similar to bacteria and virus mutations developing antibiotic resistance, spam bots are becoming more resilient in penetrating Internet firewalls and security layers.

Real-time email validation. Is email real or Not.

It is very important to be sure that the user used his real email address. Spambots very often use fake email addresses, i.e. which addresses do not exist.

CleanTalk will check email addresses for existence in real time.

Non-existing email addresses also entail several other problems for website owners.

  • You can never contact them by email,
  • the client will never receive any notifications from you (account activation letter, password recovery, email distribution, notifications, etc.),
  • if you use email marketing for your clients, then a large number of nonexistent emails in the mailing list may result in your IP address being added to various blacklists of email servers.

Preguntas frecuentes

¿Por qué me envían spam?

Spammers want to get backlinks from your site to improve their site’s PageRank or redirect your visitors to malicious sites.This level of spam can damage your reputation with readers and commentators if you fail to tackle it. It is not uncommon for some WordPress websites to receive hundreds or even thousands of comments every week. However, by using a CleanTalk plugin, spam can be easily handled by your WordPress website.

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 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.

¿Te protege el plugin de la fuerza bruta, ataques DoS y ataques de spam?

Sí, lo hace. Por favor, activa la opción ‘SpamFirewall’ en la configuración del plugin para proteger tu web de DoS/DDoS, ataques XMLRPC.

How does the plugin stop spam?

Por favor, ten en cuenta – las acciones del administrador no se están comprobando.

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. Correo Electrónico, IP, comprobar la entrada de actividad de spam de dominio. El plugin utiliza la base de datos en línea en la actividad de spam, que consta de más de 20 millones de registros de actividades spam de los IPs, correo electrónicos, dominios y ASN. Si el IP o el correo electrónico del remitente está en la base de datos, el remitente recibe algunas puntuaciones de spam. Para reducir la tasa de falso/positivo el plugin no sólo utiliza la prueba de lista negra para prohibir los spammers, el remitente será prohibido cuando, y sólo cuando las pruebas múltiples de spam han fracasado.
  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.
¿El plugin antispam protegerá mi tema?

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.

¿Puedo utilizar CleanTalk con 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.

¿Es CleanTalk mejor que Akismet?

Please look at this features comparison here

¿Puedo utilizar CleanTalk para eliminar la espera de comentarios de spam?

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?

El plugin comprueba todos los comentarios que no son spam en la base de datos de lista negra y sabrá cuáles son los remitentes de correo no deseado que tienen actividad en otros sitios web.
Hay algunas diferencias entre la base de datos de lista negra y API para protegerle de registros/comentarios de spam bots en línea. Las listas negras muestran toda la historia de la actividad de spam, pero nuestra API (que se utiliza en las pruebas de spam) también se basa en otros parámetros: último día de la actividad, el número de ataques de spam durante los últimos días, etc. Estos mecanismos nos ayudan a reducir el número de resultados falsos. Por lo tanto, no hay nada extraño, si algunos emails/IPs no son encontrados por los comentarios a granel/cuentas de prueba.

Para revisar los comentarios por favor vayan aquí:

WordPress console -> Comments -> Find spam comments

Para revisar los usuarios por favor vayan aquí:

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 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.

¿Puedo utilizar CleanTalk con plugins de caché?

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.

¿Es CleanTalk compatible con 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.

¿ Es CleanTalk compatible con una red de distribución de contenidos (CDN)?

Sí, lo es. CleanTalk funciona con cualquier sistema de CDN, es decir, CloudFlare, MaxCDN, Akamai.

¿Puedo utilizar la funcionalidad de CleanTalk en mis plugins?

Yes, you can. Just use following snippet:

    include_once( ABSPATH . '/wp-content/plugins/cleantalk-spam-protect/cleantalk.php' );
//for registration test:
$res=ct_test_registration("nickname", "", "");
//or for some other messages (contact forms, comments etc.)
$res=ct_test_message("nickname", "", "", "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


define('CLEANTALK_AJAX_USE_FOOTER_HEADER', false); //false - don't use wp_footer() and wp_header() for including AJAX script, true - use it
¿Puedo añadir exclusiones para algunas páginas de mi sitio?

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: If you need to except these URLs:
You should type this in wp-config.php:

$cleantalk_url_exclusions = array('some');
Can I add exclusions for some IP addresses?

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

$cleantalk_ip_exclusions = array('', '');

Now, all requests from IP and 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.

¿Qué No puedo enviar mis datos personales a los servidores CleanTalk?

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 Spam FireWall?

Use special IP in URL to test Spam FireWall. For example,
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:

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

¿Funciona el plug-in con 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.

¿Cómo cerrar la renovación o el aviso de prueba en el backend de WordPress?

Para cerrar el aviso por favor, guarde la configuración del plugin de nuevo o que se cerrará automáticamente en el plazo de 60 minutos después de la renovación.

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:

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?

The following possibilities are available for you in the Anti-Spam Log:

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

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

  • Filter spam records by your websites.

  • Filtrar los registros de spam por país de donde provienen.

  • Filtrar los registros de spam por dirección IP, dirección de correo electrónico o nombre de usuario.

  • Opciones disponibles para un registro específico:

    • Details – see item 4 below.
    • Spam/Not Spam – press this string if our system made wrong decision and blocked or approved a registration, a comment ot a contact form submission. More about it here:
    • Delete – delete a record permanently.
    • Personal blacklists – go to your website Black&White Lists page.
    • Record details: block reason, body of the message, additional caught data.

Gestión de comentarios de spam

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:

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.

¿Cómo informo un bot de spam perdido o un filtro incorrecto?

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
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.
When you mark a record as “Not SPAM”, its e-mail and IP-address will be added to your personal white list for your website.

¿El plugin es rápido?

We develop plugin to do it as optimized as possible, CleanTalk doesn’t downgrade response time in backend or frontend. The plugin proccess only POST requests to WordPress core, it tackes less than 1 second to return results.

Is the plugin EU GDPR compatible?

Yes, it is. Please read this article,


poor registration spam detection

I installed it mainly to clean spam registrations.
It only detected 126 of more than 800 spam registrations, so trying something else.

Also, couldn’t find an option to manually mark the spam users for the plugin to improve it’s detection.

Seriously Easy to Use

This is one of the easiest and most efficient anti-spam / security plugins I’ve ever used with WordPress!
I highly recommend it!

quirk managing account inside of WordPress

CleanTalk defaults to my login email address on a particular WordPress site when trying to enter the purchased access key.

I am trying to help clients buy their own access to CleanTalk and manage it. the Plugin automatically tries to default the set-up inside the Plugin on the WordPress site to my email address and there is no apparent way to change the account email address to the client’s. at least not clearly or in a straightforward manner.

I clicked Support to get help with this and was directed to this WordPress page.

CleanTalk Does The Job

We were using Akismet for years but it didn’t do a great job with our forms from Contact 7 or Gravity Forms so we found our way to CleanTalk. Now, our forms SPAM is solved, and we really like the Personal Blacklists and SpamFireWall, both of which combined substantially reduced the SPAM in our blog. CleanTalk is priced right, and we’ll stick with it!
