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


Anti-Spam Service


no spam, stop spamCleanTalk Anti-Spam is a cloud service protection from spam for websites. CleanTalk uses protection methods that are invisible to site visitors. Connection to the service eliminates the need for Captcha, questions and answers and other methods of protection, that complicate the exchange of information on the website.

The main function of CleanTalk is providing the owners and administrators of websites a reliable tool for protecting your web site against spam and spambots. Invisible for visitors, simple and convenient for administrators, CleanTalk blocks 99,998% of the spam. Thanks to its capabilities, CleanTalk surpasses analogs in: the accuracy of spam detection, the speed of the plugin, provides a report about the work of the service and the availability of additional option SpamFireWall.

How does it work?

  1. A visitor writes a comment or registers.
  2. CleanTalk Anti-Spam plugin sends action parameters in cloud service.
  3. The service analyzes the obtained parameters.
  4. If it's a visitor, then the comment is published. If it's a spam bot, then CleanTalk blocks this comment or registering.
  5. The parameters are written to the log, which you can see in the dashboard.

The cost of the license for one website is $8 per year.

Blocking Visitors by Country



CleanTalk provides 2 different types of blocking users by country:

  • Anti-Spam
  • SpamFireWall


Blocking by country using Anti-Spam filtration service allows you to block only comments/registrations on the site from users from certain countries. The site will be available for visitors and they can view it, but will not be able to leave a comment.

How does it work?

  • At the moment when the visitor sends a comment or is logged, the form parameters are sent to the server CleanTalk.
  • The IP address of the visitor is checked for a ban.
  • If the IP address belongs to the country for which the lock is enabled, the visitor will receive a notification.

This option is useful in cases of protection from manual spam and enhances protection. If your website isn't aimed at an international audience, and you don't expect comments/users from other countries. For example, your website is about fishing in Ireland, then there is no need for comments from Asia or Africa and you can block a comment from spam active countries.


Blocking traffic by country using Spam FireWall allows you to partially block access to the site for the IP addresses of specific countries. All visitors from the blocked country will be given a special page, while ordinary users will be able to go through it and be able to view the site, comment, and register, but bots will not be able to go through this page. This option is useful because it can significantly reduce the load on the site, since all GET requests will be blocked and the site will not execute scripts for these requests, the blocking page almost does not consume any server resources. It can be used to block brute force attacks, vulnerability scanners, various bots, as well as to temporarily block traffic in some types of DoS attacks, when attackers send thousands of HTTP requests to the site, reduce the likelihood of hacking the site.

You can enable the option in the CleanTalk Dashboard  -> Tools -> Personal lists  or use the link

We added a new filter to block comments/messages by languages. It allows you to block comments and messages in other languages automatically according to your blacklist.

At the moment, the Language Filter has the following entries:

  • Chinese
  • Korean
  • Japanese
  • Hindi
  • Arabic
  • Cyrillic

This option is useful in cases of manual spam and to enhance your website protection in general.

Spam FireWall


firewallAn additional option in the Anti-Spam plugin, blocks access to the web site with spam active IP addresses (Blocks Get requests). Spambots are blocked before they get access to the website, it prevents the loading of pages of a website spam bots, so your web server doesn't need to run all the scripts on these pages. This can reduce the load on the database and web server.

Spam FireWall is fully compatible with the most popular VPN services. Also, Spam FireWall supports all search engines Google, Bing, Yahoo, Baidu, MSN, Yandex and etc.

How does it work?

  • The user visits the website.
  • The data of the HTTP request are checked in a database containing records on more than 5,8 million IP spambots.
  • If the IP is contained in the database spambots then the Anti-Spam plugin shows a special page. Nothing happens to legitimate users - protection works invisibly. If the request was from an ordinary visitor, then 3 seconds later, he will be redirected to the website.
  • All information about the process is stored in the database and available in the dashboard.



Spam FireWall can be enabled in the plugin settings. Spam FireWall is available for WordPress, Joomla, Drupal, Bitrix, SMF, phpBB, MediaWiki, IPS Community Suite.



Personal Black Lists for SpamFireWall


It allows you to add to the lists SpamFireWall individual IP addresses and subnets. To block attacks with the IP addresses are not yet included in the SFW base. This option can help to block HTTP / HTTPS DDoS attacks, SQL attacks, brute force attacks and any other attacks that are made through the HTTP / HTTPS.

CleanTalk records all requests blocked SpamFireWall, and you can view statistics in the dashboard.

Spam FireWall and blacklists are free options and included in the cost of anti-spam service.

Checking For Spam in Existing Users And Comments


In the CleanTalk Anti-Spam plugin, we added a filtering service of checking existing users and comments for spam. These features can help to clean the website from existing spam. Options are available in plugins for WordPress, Joomla, phpBB 3.1 - 3.2, SMF, IPS. When the spam checking starts the Anti-Spam plugin collects the next information about users and comments:

- IP address

- email

- Date

Next, the status of IP and email in the CleanTalk database are checked on the date of comment or registration (here some differences are possible with the API methods, which are doing checks all time). All the spam users and comments found will be shown in a list. You can choose records to delete or delete all records.

Also, you can check bbPress topics using a special addon named CleanTalk bbPress topic scanner.

Real-Time Email Address Existence Validation

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. 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.


CleanTalk will check email addresses for existence in real-time.


Filtering Disposable & Temporary Emails

Block fake and suspicious users with disposable & temporary emails to improve email delivery. So, it also prevents malicious activity, spam bots, and internet trolls.


Anti-Flood and Anti-Crawler

Security & Firewall for WordPress


Security FireWall by CleanTalk will protect your WordPress website against Brute force hacks. The plugin is effective — it doesn't load the server, doesn't inquire the database and doesn't create any tables. It doesn't put anything in ".htaccess" as it could have a negative effect on your website accessibility or block the access to the Administrator profile.

The plugin takes optimal delay time between login attempts when a user corrects his credentials and tries to log in again. These seconds are more than enough for a user. If a user didn't make it in time — he can always retry and the delayed time will be nullified.

Every day the plugin sends a Security report to your email. The report provides data on the number of incorrect password entries and the IP addresses from which the tried to sign in. Also, the Security Audit Log keeps track of actions in the WP Dashboard to let you know what is happening on your blog.

List of features of the Security & Firewall Plugin by CleanTalk:

  • Brute-force Protection
  • Website Firewall
  • Country Blocking
  • Login Attempts and Password Searching Log
  • User Actions Log (Audit)
