Low false/positive rate This plugin uses multiple anti-spam tests to filter spam bots having as low false/positive rate as possible. 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 By default, well-known good bots — including AI crawlers such as GPTBot (ChatGPT), ClaudeBot (Claude), Google-Extended (Gemini), and Copilot — are allowed. You can choose which of these bots to block individually in your private lists. Blocking a bot will stop the corresponding AI service from accessing your content. How to protect sites from spam bots without CAPTCHA? CleanTalk Anti-Spam protects websites from spam bots without using traditional CAPTCHA, reCAPTCHA, or other visitor challenges. Instead of showing CAPTCHA puzzles, the service uses behavioral analysis, invisible JavaScript tests, and a global spam database to detect spam automatically in the background. This CAPTCHA-free anti-spam protection works for contact forms, comments, registrations, and WooCommerce checkouts without creating friction for real visitors. By replacing CAPTCHA with automated spam detection, CleanTalk helps improve usability, accessibility, and conversion rates while still blocking spam effectively. 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 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 spam bots. 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 spam bots. 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, Phones 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 email, phontes 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. Honeypot field The option helps to block bots. The honeypot field option adds a hidden field to the form. When spambots come to a website form, they can fill out each input field. Enable this option to make the protection stronger on these forms. Learn more about supported forms here.
