Frequently Asked Questions

Common questions about Anti-Spam, Spam FireWall by CleanTalk

Yes, CleanTalk stops spam in contact forms, registration forms, comments, and other forms on your website. It uses a combination of algorithms and a cloud-based database to identify and block spam submissions in real-time.

Yes, CleanTalk protects WooCommerce from fake orders and spam registrations. It checks all incoming orders and registrations against its anti-spam database and algorithms to ensure that only legitimate users can place orders or register on your site.

CleanTalk protects all WordPress forms, including but not limited to: * Comments * Registration forms * Contact forms * Sign-up forms * Search forms * Subscription forms

Spammers want to get backlinks from your site to improve their site's PageRank or redirect your visitors to malicious sites.This level of spam can damage your reputation with readers and commentators if you fail to tackle it. It is not uncommon for some WordPress websites to receive hundreds or even thousands of comments every week. However, by using a CleanTalk plugin, spam can be easily handled by your WordPress website.

Yes, it is. The plugin doesn't block mobile visitors as well as desktop website visitors. It uses several independent anti-spam tests to decrease the number of false outcomes and to have as low false-positive rate as possible. Multiple anti-spam tests help to avoid false/positive blocks for real website visitors even if one of the tests failed.

Please use the email stop_email@example.com for comments, contacts or signups to see how the anti-spam protection works. Also, you can see the logs for the last 7 days in the Dashboard or look at the folder "Spam" for banned comments.

Please, note - administrator's actions are NOT being checked. The plugin uses several simple tests to stop spammers: JavaScript anti-spam test. 99% of spam bots don't have full JavaScript functions support. So, the plugin has the code which can be run by normal visitor and can't be run by the spam bot. Email, IP, domain spam activity list entries check. The plugin uses spam activity database online at cleantalk.org, consisting of more than 20 billion spam activity records of IPs, Emails, Domains and ASN. If the sender's IP or Email is in the database, the sender gets some spam scores. To reduce false/positive rate the plugin not only uses the blacklist test to ban spammers, the sender will be banned when and only when multiple spam tests have been failed. Comment submit time. Spam bots usually submit the info immediately after the page has been loaded, this happens because spam bots don't actually fill the web form, they just send $_POST data to the blog. The normal visitor sends the data after several seconds or minutes.

The plugin does not filter trackbacks or pingbacks, but it can disable them using WordPress core functionality. To enable this option, go to: WordPress Dashboard → Settings → Anti-Spam by CleanTalk → Advanced Settings → "Disable Pingbacks and Trackbacks".

Yes, you can. The plugin has the option to test all pending comments via database of spam active IP/Email, found spam comments will be moved to Trash folder.

The plugin checks all non-spam comments in the blacklist database and shows you those senders who have spam activity on other websites. There are some differences between blacklist database and API to protect you from spam bot registrations/comments online. Blacklists show all history of spam activity, but our API (which is used in spam tests) relies on other parameters too: last day of activity, number of spam attacks during the last days etc. These mechanisms help us to reduce the number of false outcomes. So, there is nothing strange, if some emails/IPs are not found by bulk comments/accounts test. To check comments please go here: WordPress console -> Comments -> Find spam comments To check users please go here: WordPress console -> Users -> Find spam users
