Extending CleanTalk Anti-Spam

    Check existing Joomla users for spam


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

    We have implemented a spam check for comments and users who 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

    The plugin checks the creation dates of users / comments. API methodIP / email data is sent to CleanTalk servers. Next, the IP / email is checked in the CleanTalk database and if, by the date of verification, these IP / email had the BlackListed status, then the API method will return information about this to the plugin. The plugin forms a table with suspicious users / comments that can be deleted.

    To start scanning, go to the plugin settings: Extensions → Plugin manager → Antispam from CleanTalk, then click the “Check user spam” or “Check spam comments” button.

    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, USA - 33.01%, Canada - 17.93, countries of the European Union, India, Japan, Brazil grew to 21-27%.



    In 2017, we noted an increase in spam attacks with IPv6 and launched IPv6 support in anti-spam plug-ins, in the Black Lists database and API methods.

    Manage WordPress Spam Comments


    CleanTalk Anti-Spam allows you to configure actions for 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 cleaning of spam comments older than 15 days.

    Block spam comments without moving to WordPress - in this case, spam comments 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 has status in BlackListed Black Lists will be placed in the WordPress trash, the rest of the spam comments will be moved to the Spam folder. Comments containing Stop Words will be sent for manual moderation.

    Block emails / nicknames by mask


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