CleanTalk uses protection methods that are invisible to website visitors. Connecting to the service eliminates any needs of CAPTCHA, questions and answers, and other methods of protection that complicate the exchange of information on the website.


How Does It Work?

  1. A visitor writes a comment or creates an account.
  2. The CleanTalk Plugin sends action parameters to the CleanTalk Cloud.
  3. The CleanTalk Service analyzes the parameters.
  4. If it's a real visitor, their comment will be published. If it’s a spambot, then CleanTalk blocks this comment or registration.
  5. Parameters are being written to the log which can be viewed in the Control Panel service.

What Makes Us Different From Other Spam Protection Services? Why Choose Us?

  1. No Captcha or any other actions are required from the user. Captcha service lowers conversion rates, irritates customers and makes them leave your website. Captchas are unsafe and let a lot of spam in. It transfers the spam problem from the webmaster to the customer, which means that you still have spam problems but you don’t know what to do about them. You don’t know how many customers you have lost as they couldn't input the symbols correctly.

  2. It is more reliable than similar systems. Other systems let spam in; they have different operating principles and can’t be as reliable as CleanTalk. CleanTalk algorithms estimate user behavior and the way forms are being filled. These multilevel checks enable CleanTalk to reach high efficiency in spam protection. With other protection systems, real visitors might be mistaken for spam; all spam messages are being put in a spam folder and you have to take time to look through them all to not miss a client. This folder has to be cleaned all the time, which leads to more load on the website, causing it to start working slower.

  3. CleanTalk is more reliable than protection methods based on JavaScript checks. Spam bots can run JavaScript and their number grows, meaning that spam grows too. Some customers turn off the JavaScript support in their browsers for safety purposes and these customers leave your website without you even knowing about it.

  4. Clear statistics. CleanTalk delivers extremely open statistics for all incoming registrations and comments, which gives you full control of the process. You will never miss a message. In order to inform clients, CleanTalk sends a Weekly Report to your email containing information on the number of approved and blocked registrations/comments. CleanTalk provides you with diagrams for every website so you can see the dynamics of spam activity or legitimate comments/registrations on your website.

  5. CleanTalk protects all forms at once — comments, registrations, feedbacks, contacts, reviews. There is no need to install a separate plugin for a specific form.

  6. Easy to install and use. Even my grandma can do it.

  7. CleanTalk operates automatically, which saves you time and resources, letting you focus on developing and improving your website and business without being distracted by other matters.

  8. CleanTalk is a Premium Service. This guarantees that the plugin won’t disappear the way others do. You can always contact technical support and your request will be processed promptly. We provide high-quality service and therefore do not distribute a free version. Free versions always have limitations that influence the quality of spam protection.

CleanTalk anti-spam reviews



CleanTalk is one of the fastest plug-ins that allow you to lower your server load. One of the important parameters for each webmaster is the speed of your website, so we make sure that our plug-in takes as little of your server resources as possible. The Cloud Service provides advantages that all checks take place in the CleanTalk Cloud.

The CleanTalk company developed unique algorithms to assess the behavior of the visitor. CleanTalk analyzes user behavior and parameter of the filled out forms. Anti-spam module, installed on the website, sends the behavior parameters of visitors or spambots. These parameters are being estimated, and the service makes a decision — to post the visitor's message or to define it as spam and reject it. Based on such checks, the service forms its own list of email addresses used by spambots. Likewise the registrations of visitors are being checked too. The service adds not only email addresses to the blacklist, but also IP addresses and domains of the websites that are promoted through spam mailout. All of this happens automatically and requires no action from the website administration. At 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, so our team is aiming to improve those figures over time.

All-In-One. CleanTalk immediately protects all forms — comments, registrations, feedbacks, contacts. No need to install additional plug-ins for each form. You get saved resources and increased performance of your website.

Anti-Spam Log. The CleanTalk Service records all filtered comments, registrations and other spam attacks in the “Log of Spam Attacks” and stores the data in the log up to 45 days. Using the log, you can ensure reliable protection of your website from spam and no false positive filtering.

With the help of the Anti-Spam by CleanTalk you can check existing comments and users to find and quickly delete spam comments. This allows website administrators to automatically check and identify spambots, comments and users, which were not detected by conventional anti-spam tools. Existing comments and users are being checked through our database of the nearly 2 million of caught spambots. Detailed statistics allow the CleanTalk customers to control the whole process.

CleanTalk has an advanced option “Spam FireWall”. This option allows blocking the most active spambots before they get access to your website. It prevents the loading of pages of your website by spambots, so your web server doesn’t need perform all page scripts. Also, it prevents the scanning of pages of the website by spambots. Therefore Spam FireWall significantly reduces the load of your webserver. 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 infringer a block page with a description of DDoS rejection instead of your website pages. Therefore Spam FireWall helps to reduce CPU usage of your server.
