What are best practices for protecting against spambots getting into your web form? Can you elaborate why Captcha should not be used?

Please be noted that captcha fields is only effective if there is an automated attempt to send spam submissions. It cannot prevent, if there is a human attempt to send spam submissions.
You can take advantage of our "Unique Submission" feature to block multiple submissions from one system or one IP address by setting the "Loose check" or "Strict Check" respectively. The following guide should help you set unique submission: http://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form
You can also use our "Unique Question" feature to prevent from submitting duplicate submissions. Example: You can set one of your forms question (like cell number or email address) to be a unique question. This will not allow a user to use the same cell number or email address to submit your form.
