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.

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.

How does CleanTalk improve SEO for your website?

CleanTalk works faster than most of the other anti-spam plugins.

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. How does it work?

• 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: Anti-Flood & Anti-Crawler

Spam FireWall: Anti-Flood and Anti-Crawler options are intended for blocking unwanted bots, content parsing, shop goods prices parsing or aggressive website scanning bots. Learn more https://cleantalk.org/help/anti-flood-and-anti-crawler

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.

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,

• 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.
