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-aanvraag gegevens worden gecontroleerd in de bijna 5,8 miljoen van de geïdentificeerde IP-adressen van spambots.
- 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 e-mail validatie. Is e-mail echt of niet.
Het is erg belangrijk om er zeker van te zijn dat de gebruiker zijn echte e-mailadres gebruikt. Spambots gebruiken vaak valse e-mailadressen, d.w.z. welke adressen er niet bestaan.
CleanTalk zal het bestaan van e-mailadressen in real time controleren.
Ook niet-bestaande e-mailadressen brengen voor site-eigenaren een aantal andere problemen met zich mee.
- Je kunt nooit per e-mail contact met hen opnemen,
- de klant zal nooit meldingen van je ontvangen (activeringsbrief, wachtwoord herstel, e-mail distributie, meldingen, etc.),
- als je e-mailmarketing voor je klanten gebruikt, kan een groot aantal niet-bestaande e-mails op de mailinglijst ertoe leiden dat je IP-adres wordt toegevoegd aan verschillende zwarte lijsten van e-mailservers.
Improve your email list with email validation without fake emails.
Het blokkeren van wegwerp & tijdelijke e-mails
Blokkeer nep- en verdachte gebruikers met tijdelijke e-mails om de aflevering van e-mails te verbeteren. Het voorkomt dus ook kwaadaardige activiteiten, spam bots en internettrollen.
Stops Spam in Search Form
Spam bots kunnen je zoekformulier gebruiken om een GET aanvraag te doen met spam tekst. CleanTalk Anti-Spam heeft de mogelijkheid om je site zoekformulier te beschermen tegen spam bots. Elke keer genereert de zoekopdracht een nieuwe pagina en als er veel verzoeken zijn, kan dit een extra belasting veroorzaken. Dus, onder bepaalde voorwaarden, kunnen spam-zoekopdrachten worden geïndexeerd, wat van invloed is op SEO,
- Anti-Spam protection for website search forms repels spam bots.
- Als je zoekformulier te vaak gegevens krijgt, zal de CleanTalk Anti-Spam plugin een pauze toevoegen en deze bij elke nieuwe poging om gegevens te verzenden verhogen. Het bespaart je webserver processor tijd.
- 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.
Je weet altijd waar gebruikers op je site naar op zoek waren.
Reacties uitschakelen
This option disables comments on your site. You can choose one or several options:
- Schakel reacties uit voor berichten
- Schakel reacties uit voor pagina’s
- Schakel reacties uit voor 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.
