Expanding the capabilities of CleanTalk Anti-Spam

Checking existing Joomla users for spam

Spam bots messages (comments) are often disguised as regular user messages, but contain advertising links or text. The main objectives of such messages are, the transition of the user to a malicious resource, advertising or links to improve the position of their site. This compromises the site and can ruin the reputation, search engines can lower the position of the site in search results.

We implemented a spam check for comments and users that already exist on the site. This allows website administrators to automatically check and identify comments and registrations of spam bots that were not detected by conventional anti-spam tools.

How it works

Plugin checks user creation date / comments. API method, IP / email data is transmitted to the CleanTalk server. Next, there is an IP / email check in the CleanTalk database and if at the verification date these IP / emails had the status BlackListed, then the API method will return information to the plugin about it. The plugin creates a table with suspicious users / comments that can be deleted.

To start scanning, go to the plug-in settings: Extensions → Plugin Manager → Antispam from CleanTalk, then click the button “Check Spam Users” or “Check Spam Comments”.

IPv6 support

IPv6 is becoming increasingly used on the Internet. Just look at the statistics, from which it follows that in 2017, there was an increase in the use of IPv6 from 14-16% to 18.27-21.80%.



The growth leaders were: Germany- 35.27, the USA - 33.01%, Canada - 17.93, the countries of the European Union, India, Japan, Brazil rose to 21-27%.



In 2017, we celebrated the growth of spam attacks from IPv6 and launched support for IPv6 in anti-spam plugins, in the Black List database and API methods.

Manage spam comments in WordPress

CleanTalk Anti-Spam allows you to configure spam comments. The following options are implemented:

Move to spam folder - all spam comments will be moved to the Spam folder. To avoid a large number of entries in the folder, you can configure automatic spam comment comments older than 15 days.

Block spam comments without moving to WordPress - in this case, the spam comment will not be added to any of the WordPress folders, information about each post will be available only in the CleanTalk control panel.

Smart sorting of spam comments - in this case, spam comments for IP / email that have status in BlackListed Black Lists will be placed in the WordPress recycle bin, the rest of the spam comments will be moved to the Spam folder. Comments containing Stop Words will be sent for manual moderation.

Lock emails / nicks by mask

This option refers more to moderation and allows you to prohibit the use of certain words in user nicknames based on a mask, for example, email *kkkvvvv*@example.com, while all addresses with any character set before “kkk” will be blocked, before “ vvv ”and after“ vvv ”.
