Private black lists for anti-spam service Automatically block comments and registrations from your private black IP/email address list. Hide «Website» field for comments This option hides the «Website» field from standard WordPress comments forms. After that spammers won’t be able to send spam links using «Website» field in the bottom of the comments form. 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.

I will make a request on make/polyglots to have you added as validator for this plugin/locale. How to choose an antispam plugin When you look through the WordPress Plugin Repository you will see more than a hundred antispam plugins. Which one is the best one? Short answer, there is no “best one”. No spamfilter and no method for spamfiltering is perfect. Slightly longer answer, you could try about twenty and choose the one that fits your needs best. But there is also a really long answer. There are different methods that can be used against spam, and every method has its drawbacks. In my opinion, having a low number of false positives is more important than perfectly marking all spam, you don’t want to miss out on important people or information. Nagging the user in some way has a similar effect, the user might not even want to bother with that and just walk away. Third party services: Services like Akismet, OOPSpam, Stop Forum Spam and also reCAPTCHA offer third party services to check for spam. This can be very effective, but you are giving user submitted data away to these third parties and are also giving your users up for tracking them. Captcha’s, reCAPTCHA and Quizz Questions: You are annoying your users and probably sending some of them away. This especially counts for reCAPTCHA for visitors who have third party cookies disabled. Blacklists: Often running behind the facts. That goes for the way of getting users off that list, and also in getting users on that list. Referer check: check if the Referer header is set correctly. You can never trust it is set correctly. Modern browsers are limiting the use of Referers, though for now that is mostly for third-party domains. JavaScript methods: Spammers often (always?) don’t use JavaScript, they just post the form with spammy data. Drawback for this method is that statistics say that about 1 percent of users has JavaScript disabled. Also, some websites have broken JavaScript, which might make the spamfilter break as well. Activation email for registering users. Users only get activated after clicking a link in an activation email. You still have all the non-activated users in your site however. You could have a bright idea about combining several methods, but then you get the drawbacks of all the methods you use. Another complication of choosing a good plugin is that most antispam plugins don’t tell you what methods they use. The documentation doesn’t tell you, and looking at the source code just leaves you confused at the chaos that it often is. My main motivation for writing this plugin is to offer a plugin that does spamfiltering with JavaScript methods in a simple and effective way. The claimed 1 percent of users that has JavaScript disabled will also be tech-savy enough to enable it again for your website. Compatibility This plugin is compatible with ClassicPress. Contributions This plugin is also available in Codeberg.
