large plugin functionality, the developers have optimized the performance of
the plugin so that AntiSpam by CleanTalk is faster than most analogs. This contributes to the cloud service architecture, as all calculations take place in the cloud, not on the server, the server receives the finished result for further action.

Using the log, you can ensure reliable protection of your website from spam and no false/positive filtering.
= Spam FireWall =
CleanTalk has an advanced option "Spam FireWall". Spam FireWall allows blocking the most active spam bots before they get access to your website. It prevents spam bots from loading website pages so your web server doesn't have to perform all scripts on these pages. Also it prevents scanning of pages of the website by spam bots. Therefore Spam FireWall significantly reduces the load on your web server. Spam FireWall also makes CleanTalk the two-step protection from spam bots. Spam FireWall is the first step and it blocks the most active spam bots. CleanTalk Anti-Spam is the second step and checks all other requests on the website in the moment of submitting comments/registers etc.
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 Spam FireWall works? =
* The visitor enters to your web site.
* HTTP request data are being checked in the nearly 5.8 million of the identified spam bot IPs.
* If it is an active spam bot, the bot gets a blank page, if it is a visitor then he receives a normal page. This process is completely transparent for the visitors.
All the CleanTalk Spam FireWall activity is being logged in the process of filtering.
= Spam FireWall DDoS Protection =
Spam FireWall can mitigate HTTP/HTTPS DDoS attacks. When an intruder makes GET requests to attack your website, Spam FireWall blocks all requests from bad IP addresses. Your website gives the intruder a special page with the description of DDoS rejection instead of the website pages. Therefore Spam FireWall helps to reduce CPU usage of your server.

= How to protect sites from spam bots without CAPTCHA? =
The most popular anti spam method is CAPTCHA - the annoying picture with curved and sloping symbols, which are presented to the visitor to decipher and fill in. In is supposed that spam bots won't discern these CAPTCHA, but a visitor will. CAPTCHA provokes great irritation, but if the visitor wants to comment, he has to fill in these symbols time after time, making mistakes and starting once again. Sometimes CAPTCHA reminds us of the doodles of a two year old child. For users with vision problems CAPTCHA is an insurmountable obstacle. Users hate captcha. Captcha for users means "hate". Unreadable CAPTCHA stops about 80% of site visitors. After 2 failed attempts to decipher CAPTCHA 95% of visitors reject further attempts. At the sight of CAPTCHA and after input errors, many visitors leave the resource. Thus, CAPTCHA helps to protect the resource spam both from bots and visitors. CAPTCHA is not a panacea from spam. Doubts concerning the Need for CAPTCHA?
*"Ultimately, CAPTCHAs are useless for spam because they're designed to tell you if someone is 'human' or not, but not whether something is spam or not." Matt Mullenweg*
You do not have to work in IT to know what spam is. Besides piles of unwanted email, there are spam bots, or special software programs designed to act as human website visitors that post unwelcome messages over the Internet to advertise dubious services. More often than not spam messages do not even make sense. Similar to bacteria and virus mutations developing antibiotic resistance, spam bots are becoming more resilient in penetrating Internet firewalls and security layers.
= CleanTalk's features =
Anti-Spam by CleanTalk with Spam FireWall is one of the fastest plugins that allows you to lower the server load. One of the important parameters for each webmaster is the speed of the site, so we make sure that our plugin consumes as few server resources as possible. The Cloud Service provides the advantage: all data processing takes place in the Cloud.
CleanTalk team has developed unique anti spam algorithms to assess visitors behavior. CleanTalk analyzes user behavior and the parameters of the filled forms. Our anti-spam module, being installed in your website, sends the behavior parameters of either a visitor or a spam bot. When these parameters are estimated, the anti spam service makes a decision - to post a message or to define it as spam and reject it. Based on these checks, the service forms its own list of email addresses used by spam bots.
The registrations of visitors are being checked in a similar manner. The service adds to the blacklist not just email addresses, but also IP addresses and domains of websites that promote themselves through spam mailing. All of this happens automatically and requires no action from the administration of the website. In 2.5 million queries the service makes a mistake in 40-45 cases, i.e. CleanTalk detects spam with 99.9982% accuracy. We constantly monitor these errors and make adjustments to our algorithms. Even with this exceptional accuracy our team is aiming to improve the figures over time.
All-in-one. CleanTalk protects form spam all forms instantaneously - comments, registrations, feedback, contacts. No need to install additional plugins for each form. You save resources and increase performance of your website.
Spam attacks log. Anti-Spam by CleanTalk records all filtered comments, registrations and other spam attacks in the "Log of spam attacks" and stores the data in the log for up to 45 days. Using the log, you can ensure reliable protection of your website from spam and experience no false/positive filtering.
With the help of anti-spam by CleanTalk you can check existing comments and users, to find and quickly delete spam comments at once. This allows administrators of websites to automatically check and identify spam bots, comments and users, which were not detected by conventional anti-spam tools. The existing comments and users checking process is performed in a database of the nearly 2 million identified spam bots. Detailed spam stats allows CleanTalk customers to fully control it.
CleanTalk has an advanced option "Spam FireWall". This option allows you to block the most active spam bots before they get access to your website. It unloads you website pages when an attempt attack was made, so your web server won't run unnecessary scripts on these pages. Also it prevents any scanning of website pages by spam bots. Subsequently Spam FireWall significantly reduces your webserver load. Spam FireWall can mitigate HTTP/HTTPS DDoS attacks. When an intruder makes GET requests to attack your website, Spam FireWall will block requests from bad IP addresses. Your website gives the intruder a special page with a description of DDoS rejection instead of the website pages. Spam FireWall can help to reduce the CPU usage of your server because of this reason.
"CleanTalk team has been developing a cloud spam protection system for five years and has created a truly reliable anti-spam service designed for you to guarantee your safety".

Auto-updating system will work from CleanTalk AntiSpam version 5.88
= Real-time email validation. Is email real or Not. =
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.
CleanTalk will check email addresses for existence in real time.
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.
Improve your email list with email validation without fake emails.
= 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.
= Stops Spam in Search Form =
Spam bots can use your search form to make a GET request with spam text.
CleanTalk Anti-Spam has the option to protect your website search form from spam bots. Each time, the search generates a new page and if there are many requests, this can create additional load. So, under some conditions, spam searches can be indexed, which affects SEO,
* Spam FireWall blocks access to all website pages for the most active spambots. It lowers your web server load and traffic just by doing this.
* Anti-Spam protection for website search forms repels spambots.
* If your search form gets data too often the CleanTalk Anti-Spam plugin will add a pause and increase it with each new attempt to send data. It saves your web server processor time.
* Spam protection allows you to not forbid indexation for the crawler bots if you really need it but simultaneously you will get protection from spambots.
You will always know what users were looking for on your site.
= Disable comments =
This option disables comments on your site. You can choose one or several options:
* Disable comments for posts

[youtube https://www.youtube.com/watch?v=SktF0s-go6A ]
**Important!** To test spam protection you must post a dummy submissions as website visitor (use must logged out from WordPress console), because the plugin doesn't filter submissions from WordPress administrators.
= How can setup plugin in WPMU version? =
In WordPress multisite version you can switch the plugin to use Global Access key. In this way the plugin doesn't show any options to enter Access key in plugin settings and doesn't show Trial banner in WordPress backend. To setup global CleanTalk access key for all websites in WPMS, define constant in your wp-config.php file before defining database constants:
define('CLEANTALK_ACCESS_KEY', 'place your key here');
**Make it before you activated the plugin. If the plugin already activated, deactivate it and add the code and active it again.**
Now, all subsites will have this access key.
= Manage and control spam protection =
Go to Dashboard at the cleantalk.org or use Android, iPhone anti-spam app to manage and control spam protection.
== Frequently Asked Questions ==
= Why are they spamming me? =
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.
= Is the anti-spam protection safe for mobile visitors? =
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.
= What does the plugin do with spam comments? =
Spam comments are being moved to SPAM folder by default or you can set the option to ban spam comments silently.
= How can I test the anti-spam protection? =
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.
= Is the plugin effective against spam bots? =
The plugin Anti-Spam by CleanTalk stops up to 99.998% of spam comments, spam signups (registrations), spam contact emails, spam subscriptions, spam bookings or spam orders.
= Does the plugin protect from brute force, DoS attacks and spam attacks? =
Yes, it does. Please turn the option 'Spam FireWall' on in the plugin settings to protect your website from DoS/DDoS, XML-RPC attacks.
= How does the plugin stop spam? =
Please, note - administrator's actions are NOT being checked.
The plugin uses several simple tests to stop spammers:
1. **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.
1. **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.
1. **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.
= Will the anti-spam plugin protect my theme? =
Yes, it will. The Anti-spam by CleanTalk is compatible with any WordPress theme.
= What about pingback, trackback spam? =
The plugin passes pingbacks without any checks by default. All trackbacks will be blocked if the sender had spam activity.
= Can I use CleanTalk with Akismet? =
Sure, you can use CleanTalk with Akismet. In this case you will probably have higher false/positive rate (when legitimate comments/signups are being denied), but you will have stronger anti-spam protection on your website.
= Is CleanTalk better than Akismet? =
Please look at this features comparison here https://cleantalk.org/cleantalk-vs-akismet
= Can I use CleanTalk to remove pending spam comments? =
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.
= How does the plugin find spam in pending comments or registered accounts? =
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
= Should I use other anti-spam tools (Captcha, reCaptcha and etc.)? =
CleanTalk stops up to 99.998% of spam bots, so you can disable other anti-spam plugins (especially CAPTCHA-type anti-spam plugins). In some cases several anti-spam plugins could conflict with each other, so it would be better to use just one plugin.
= Is the plugin compatible with WordPress MultiUser (WPMU or WordPress network)? =
Yes, the plugin is compatible with WordPress MultiUser. Each blog in multisite environment has individual anti-spam options for the protection from spam bots.
= After the installation I noticed that the number of spam attacks has been increased in the stats =
There are a few reasons for this:
* With the indexing of your web-site by the search systems, appearance of external links and better search results position, your web-site attracts more and more spambots.
* Non-transparent protection systems like CAPTCHA or question/answer, that don't have spam attacks stats, don't let you see the whole picture, or the picture is incomplete.
* Counting methods for spam attacks and spam bots are different for different systems, thus the diversity appears. We seek to provide detailed stats.
= Why my dummy "spam" comment passed to the WordPress? =
The plugin has several options to detect spam bots and humans. If you just post spammy text like this:
"I want to sell something", "Buy something here.." and etc
the comments will be passed, because the plugin detects sender as a human. So, use special email *stop_email@example.com* to test the anti-spam functionality or wait a few days to see how the plugin works.
= Is it free or paid? =
The plugin is free and distributed under the GPLv2 license.
CleanTalk anti-spam plugin works with a cloud base anti-spam service and this plugin is a Software as a service (SaaS).
CleanTalk it’s a free plugin that works with premium Cloud Anti-Spam service.

= Can I use CleanTalk with cache plugins? =
Anti-spam by CleanTalk doesn't use static HTML code in its templates, so all anti-spam functions work correctly with any WordPress cache plugins.
= Does the plugin protect from spam bots if I use forms with third-party services? =
Yes, it does. Plugin protects web-forms on your websites which send data to third-party servers (like MailChimp). To enable this protection set the option 'Protect external forms' in the plugin settings.
= Does CleanTalk compatible with Cloudflare? =
CleanTalk is fully compatible with CloudFlare. Service doesn't filter CloudFlares IP's (AS13335) through blacklists database, so in this case plugin/service filters spam bots using other anti-spam tests.
= Is CleanTalk compatible with a content delivery network (CDN)? =
Yes, it is. CleanTalk works with any CDN system, i.e. CloudFlare, MaxCDN, Akamai.
= Can I use CleanTalk functionality in my plugins? =

Settings -> CleanTalk -> Advanced settings
Now the plugin will protect WordPress comments, registrations and most of popular contact forms, but will not protect some of rarely used contact forms.
= Does the anti-spam plugin work with Accelerated Mobile Pages (AMP)? =
Yes, it does. But you have to turn off the SpamFireWall and the option 'Use AJAX for JavaScript check' in Advanced settigns of the plugin to be fully compatible with Accelerated Mobile Pages.
= How to close renewal or trial notice in the WordPress backend? =
To close the notice please save the plugin settings again or it will be closed automatically within 60 minutes after the renewal.
= I'm using PHP 4.2 version and i'm getting errors related with JSON. Why does it happens? =
СleanTalk is no longer supports PHP lower than 5.2 version because the support code have incompatibility with PHP 7 version. Please, upgrade your PHP. If you couldn't perform that, let us know about it via support ticket here: https://cleantalk.org/my/support.
= Should I change anything in the plugin's settings or in my CleanTalk Dashboard when I switch my website from HTTP to HTTPS or vice versa? =

= Spam Comment Management =
By default, all spam comments are placed in the spam folder, now you can change the way the plugin deals with spam comments:
1. **Move to the Spam folder.** All spam comments will be placed to the folder "Spam" in the WordPress Comments section except comments with Stop-Words. Stop-Word comments will be always stored in the "Pending" folder.
You can prevent the proliferation of Spam folder. It can be cleaned automatically using the option "Keep spam comments for 15 days." Enable this option in the settings of the plugin: WordPress Admin Page -> Settings -> Antispam by CleanTalk -> Advanced settings -> enable "Keep spam comments for 15 days" -> Save Changes.
2. **Move to Trash.** All spam comments will be placed to the folder "Trash" in the WordPress Comments section except comments with Stop-Words. Stop-Word comments will be always stored in the "Pending" folder.
3. **Ban comments without moving to WordPress backend.** All spam comments will be deleted permanently without going to the WordPress backend except comments with Stop-Words. Stop-Word comments will be always stored in the "Pending" folder.
What comments were blocked and banned can be seen in the Anti-Spam Log here: https://cleantalk.org/my/show_requests?int=week
To manage the actions with spam comments, go to the Control Panel, select the website you want to change the actions for and go to "Settings" under the name of the website.
