How to prevent bots from automatically submitting forms?

Question

I am running ColdFusion MX, so I have no way to use the built -in cfimage Captcha function in my application, before submitting the form.

But the problem is not that bots transmit forms.

What would be the best way to prevent automatic sending?

Answer 1

Take a look at cfformprotect - it will work with CFMX 6 and all later versions.

It aims to be fully accessible and invisible to most users - with a set of methods to stop bots and spammers.

CF- reCaptcha, CFMX 7.
