How to prevent autoregistration through CRUMBS

What are crumbs?

[pushparaj]

Hello all,

Captchas are used to prevent auto registration or prevent repeated mailing thro javascript or php.

I don't want to use CAPTCHAS. How to use CRUMBS so as to do this?
What are crumbs?

Any one help me?

Thanks in advance ,

I have recently seen some sites using simple math questions as a sort of captcha. Have a randomly generated math question such as 3 + 4 + 1 that the user must answer correctly to register/post.

As for CRUMBS I haven't heard that term before.

Perhaps "crumbs" refers to the method of generating a unique, single use "token" on the form page that must be passed to the script that processes the form?

I could see how that could be considered a trail of breadcrumbs, well a trail of one breadcrumb. :)
