Block spam bots on WordPress without a CAPTCHA
Most WordPress spam is automated. Bots scrape your forms, fill them at machine speed, and submit in bursts. QWeb Spam Shield is built to catch that behaviour with invisible traps, so you block the bots and never challenge a real person.
How spam bots actually work
A spam bot does not behave like a human. It fills hidden fields a person never sees, submits a form in under a second, and fires many requests from one source. Each of those tells is something you can detect without ever showing a CAPTCHA.
How Spam Shield blocks bots
- Honeypot fields that humans never fill but bots do.
- Submit-timing checks that flag machine-speed submissions.
- Velocity and reputation limits that stop bursts and known-bad IPs.
- AI content scoring for the smarter bots that get past the simple traps.
This works the same across contact forms, comments, user registration and WooCommerce checkout, so there is one bot defence for the whole site.
Good for developers and client sites
If you manage sites for clients, you get one plugin that handles bot abuse everywhere, with a log that shows exactly what was blocked and why. No CAPTCHA support tickets, no puzzles for the client to complain about.
Common questions
