Public reviews

CleanTalk – Cloud-Based Anti-Spam Service to Keep Your Site Bot-Free.
NewsWatch Review.

Using CleanTalk on WPLift was a great test as we receive huge amounts of spam.
Oliver Dale, WPLift.com.

I know you have heard of a number of anti-spam plugins. But you must know, the cloud-based ones are the best regarding detection rate. They compare all the content in forms with their own algorithm to find out the legibility.
www.techwibe.com

The key selling point of CleanTalk for me is not simply its effectiveness. It’s the fact that CleanTalk works in the background. It does not make users jump through hoops in order to submit a comment or complete a form.

CleanTalk works faster than most of the other anti-spam plugins. It is common knowledge that the faster your site loads, the better your customer experience is, the better your SEO will be, and the better your site will convert. Speed is becoming increasingly important in SEO, conversion and user experience. Today, site speed is one of the most important ranking factors on Google. A site that loads slowly will lose visitors and potential revenue.

There are different ways of improving your site’s loading performance. One important parameter for site performance is to install well-developed plugins from a reputable source.

large plugin functionality, the developers have optimized the performance of

your safety.

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 for 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 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
  • Disable comments for pages
  • Disable comments for media

When using Disables comments, existing comments will not be deleted and will remain on the pages.

Email Address Encoder

CleanTalk Anti-Spam offers a feature called “Encode contact data” that is designed to encode all email addresses on the website pages. Encoding the email addresses increases the level of protection of contact data from being abused, parsed, getting spammed and used in spam mailing lists by bots and online criminals.
To reveal the encoded email address simply click on it and it will be decoded instantly.
