Block Bad Bots and Spam Traffic on Your Website

Bad bots flood your forms, comments, registrations and WooCommerce store with spam submissions, fake accounts and junk orders. CleanTalk blocks bot and spam traffic automatically - server-side, with no CAPTCHA for your real visitors.

One plugin protects your whole site, backed by a shared cloud blacklist of known spam IPs, emails and domains.

How CleanTalk stops bot and spam traffic

  • Blocks spam bots everywhere - comments, contact forms, registrations, WooCommerce orders and subscriptions, from one setup.
  • Shared cloud blacklist - known spam IPs, emails and domains reported across the CleanTalk network are blocked before they reach you.
  • Invisible - no CAPTCHA - real visitors never solve a puzzle, so your conversion stays intact.
  • Works everywhere - WordPress, WooCommerce, popular form plugins, and any custom site via the anti-spam API.

What bad bots do to your site

Automated bots scan the web for open forms and signup pages, then hit them at scale. Left unblocked, bot and spam traffic quietly damages your site:

Spam comments

Junk links and spam text pile up under your posts and hurt moderation and SEO.

Fake registrations

Bots create fake accounts that bloat your database and skew your stats.

Contact form spam

Your inbox fills with junk submissions and phishing attempts.

WooCommerce abuse

Fake orders, spam registrations and review spam clutter your store.

Subscription spam

Bots flood newsletter and subscription forms with junk addresses.

Scraping & harvesting

Bots crawl your pages to grab emails and content for spam lists.

Powered by shared block lists

CleanTalk maintains a live, shared spam blacklist built from activity across millions of protected sites. When a form, comment or order comes in, CleanTalk checks the sender against these block lists and its behavioral signals - all server-side, in the background.

  • IP block list - addresses with a history of spam and bot activity.
  • Email & domain block list - known disposable and spammer addresses.
  • Behavioral checks - suspicious timing and submission patterns.

Because a bot flagged on one site is known across the whole network, new spam sources are blocked faster than any single site could manage alone.

Block spam without hurting conversion

Every visible CAPTCHA is a tax on real users - forms lose completions, mobile users abandon, and screen-reader users can get stuck. CleanTalk blocks bot and spam traffic invisibly, so genuine visitors never pay for the bots' behavior. If the goal is simply less spam, server-side filtering reaches it without friction.

FAQ

How do I block bot traffic on my website?

Install CleanTalk and connect the service. It then checks every form, comment, registration and order against a shared spam blacklist and behavioral signals server-side, and blocks bot and spam traffic automatically - no CAPTCHA required.

How do I stop spam bots without a CAPTCHA?

CleanTalk filters the submission itself instead of challenging the visitor. Spam is rejected in the background, so real users never see a puzzle or checkbox.

Does it work on WordPress and WooCommerce?

Yes. One plugin covers WordPress comments, registrations and contact forms, and WooCommerce orders, registrations and reviews. Any custom site can use the anti-spam API.

Will it block real visitors by mistake?

CleanTalk is built to filter spam submissions, not genuine users. Real visitors are not challenged, and every blocked entry is logged with a reason in your dashboard so you can review it.

How much does it cost to block spam bots?

From €10/year for one site, with a 7-day free trial. There are no API-call limits and no per-form fees.
