详情介绍:

Simple No-Bot uses javascript to detect if Contact Form 7 is being submitted by a spam bot. We wrote this when clients were reporting hundreds of bogus contact forms were getting past Honeypot, but did not want to add a captcha that would impact conversions. This lightweight script has been extremely effective for eliminating spam messages from Contact Form 7 (and other forms) submissions. It does not pretend to be a complete anti spam solution.

常见问题:

Why not just use Recaptcha 3?

Google is great and all, but with every recaptcha, font, map or tag you use, you are passing each visitor's usage information to Google and strengthening their control over the web.

How does it work?

The browser automatically generates data from input events and passes it to the server via XHR. The server generates a unique token, stores a session in a transient record and returns token to the browser. The browser then injects a new input field to WPCF7 form that contains token. When form is submitted, SNB rejects the form if no corresponding transient exists (among other things).

Does it work without Javascript

No. Contact forms will fail if Javascript is not enabled.

Does it require cookies?

Not currently. We may add more behavioral analysis if the latest generation of JS-empowered bots continues to proliferate.
