Low false/positive rate
This plugin uses multiple anti-spam tests to filter spambots with a 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.

How effective is CleanTalk
Accurately blocking spam is not an easy thing to do, but CleanTalk has a very low proven False/Positive rate. Here is an actual statistics on false positives for all customers.

Registrations - 0.007%
Comments - 0.001%
Contact forms - 0.001%

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.

Spam FireWall
CleanTalk has got an advanced option "Spam FireWall", this option allows blocking the most active spambots before they get access to a website. It prevents the loading of pages of the website by spambots, so your web server doesn't need to perform all scripts on these pages. Also, it prevents the scanning of pages of the website spambots. Therefore Spam FireWall significantly can reduce the load on your web server.

Spam FireWall also makes CleanTalk the two-step protection from spambots. Spam FireWall is the first step and it blocks the most active spambots, CleanTalk Anti-Spam is the second step and it checks all other requests on the website at the moment before submitting comments/registers and etc.

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.

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.

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:
Personal blacklists are a very flexible and powerful tool, you can block or allow IP address, email address or mask e-mail (*@mail.com - will block/allow every address ending on @mail.com)

• Anti-Spam Service
  Automatically block comments and registrations from your private black IP/email address list. This option helps to strengthen the protection from 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.

• SpamFireWall
  It allows you to add individual IP addresses and subnets to SpamFireWall. It blocks the attacks from IP addresses which are not included in the SFW base yet. This option can help to block HTTP/HTTPS DDoS, SQL, brute force attacks and any others that made it through the HTTP/HTTPS. You can add not only the certain IP addresses but also a separate subnet to your personal blacklist.

Check existing comments and users for spam. Bulk removal

With the help of anti-spam by CleanTalk, you can inspect through existing comments and users to find and quickly delete spam comments/users at once. To use this function, go to plugin settings: Extensions -> Plugin Manager -> Anti-spam by CleanTalk then click the button “Check spam users” or “Check Spam comments”.

How it works: the plugin takes the data of each comment (IP/email and date), by the comment date or the user registration date, it is checked what the IP/email status in the CleanTalk blacklist database was for that date. Based on this data a list of deletions is generated, which you can edit.

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.

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.

How does Spam FireWall work?
The visitor enters to your website.
HTTP request data is checked of the nearly 5,8 million of certain IP spambots.
If it is an active spam bot, it gets a blank page, if it is a visitor then it gets a site page. This is completely transparent to the visitors.
All the CleanTalk Spam FireWall activity is being logged in the process of filtering.

Spam FireWall DDoS Protection (Experimentally option)
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 infringer a special page with a description of DDoS rejection instead of the website pages. Therefore Spam FireWall can help to reduce CPU usage on your server.

How to protect sites from spambots without CAPTCHA?
The most popular method is CAPTCHA -- the annoying picture with curved and sloping symbols, which are offered to the visitor to fill in. It is supposed that spambots won't discern these CAPTCHA, but a visitor will. CAPTCHA provokes great irritation, but if one wants to speak out, he has to fill in these symbols time after time, making mistakes and starting once again. Sometimes CAPTCHA reminds doodle 2x year old child. For users with vision problems, captcha is just an insurmountable obstacle. Users hate captcha. Captcha for users means "hate". Unreadable CAPTCHA stops about 80% of site visitors. After 2 failed attempts to bring it up to 95% reject further attempts. At the sight of CAPTCHA and after input errors, many visitors leave the resource. Thus, CAPTCHA helps to protect the resource both from bots and visitors. CAPTCHA is not a panacea from spam.
