Antispam by CleanTalk 1.1-pl

Released Feb 05, 2019 by cleantalk

CleanTalk completed the development extension for the MODX, to protect your website against spam and spambots.


The anti-spam extension is compatible with MODX versions v1.x. and approved on the MODX official marketplace.


This extension allows users to quickly and easily connect to CleanTalk anti-spam service. Its service provides 100% protection from spambots and provides a simple and convenient commentary/sign-up form for visitors.


This extension allows protection from automatically distributed spam, as well as from spambots registrations. The protection method offered by CleanTalk allows users to switch from the methods that trouble the communication (CAPTCHA, question-answer etc.) to a more convenient one.


CleanTalk saves time and resources spent on moderation and verification of questionable users or comments. Unnoticeable Protection from spam and registration forms, which does not require the visitor to prove who they are, increases the conversion in registration and is not annoying.


CleanTalk is a cloud service, security module, installed on a website, which sends the behavior parameters of the visitor or spambot. These parameters are estimated, and the service makes a decision – to post a message or to define it as spam and reject.


On the basis of such checks, the service forms its own list of email addresses used by spambots. Likewise, the registration of visitors is checked. 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. The CleanTalk company developed unique algorithms to assess the behavior of the visitor, and with 100% accuracy, we keep spam messages at bay. All of this happens automatically and requires no action from the administration of the website.


Low false/positive rate

CleanTalk uses multiple anti-spam tests to filter spambots with lower false/positive rate as possible. Multiple anti-spam tests avoid false/positive blocks for real website visitors even if one of the tests failed.

Spam attacks log

Service CleanTalk (this plugin is a client application for CleanTalk anti-spam service) records all filtered comments, registration 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.

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.

Blocking  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.

Private blacklists

Automatically block comments and registrations from your private black IP/email address list. This option helps to strengthen the protection from a manual spam or block unwanted comments from users. You can add not only the certain IP addresses but also a separate subnet to your personal blacklist.

Blocking comments by "stop words"

You can block comments which contain "stop words" to enhance spam filtering and messages with obscene words blocking. You can add particular words or phrases.

Blocking users by country

Automatically block comments and registrations from the countries you have set a ban for. This option is useful in cases of manual spam protection and for protection enhancement. If your site is not intended for an international audience and you do not expect comments/users from other countries
