Are captchas need for my online form

Question

I have an online form in asp.net which using the jQuery wizard, and was not sure my last stage would need a captcha control to prevent bots/crawlers.

So would I need a captcha? for my online web form...?? Is it recommended??

Answer 1

Captcha is recommended if your application/form is being attacked by bots. If you feel, there are attacks and you have sensitive information, you can opt for captcha (or recaptcha).

Answer 2

That's entirely up to you.

Answer 3

If you are not going to make it public, i.e. providing form to invited users only, then, you probably don't need Captcha. But, if it is going to be open to public,(like gmail for example) then, its definitely recommended to put captcha in the form.
