Spam protection for MyBB without CAPTCHA, image verification or security questions.
CleanTalk checks every new registration, thread, reply and contact form message in the cloud and blocks spam bots before they reach your forum. Real members register and post as usual, with nothing to solve.
What it protects- Registrations - spam bots are rejected with a clear message
- New threads and replies from new members
- Post edits
- Contact Us form
- SpamFireWall - blocks known spam bots before they load your pages, which also reduces server load
How it decides
CleanTalk checks the sender, not the browser: email and IP reputation collected from 1,100,000+ websites, behavior on the page and the message text. That stops bots and people who type spam by hand. Known spammers get "Forbidden. Sender blacklisted", addresses that do not exist are rejected too, real members pass.
Replace image verification and security questions
MyBB's built-in image verification and security question can be switched off: CleanTalk does the job invisibly, so you stop losing real members at the registration form.
