    How do you prevent a competitor from access content on a form?

    Asked by blundgren on June 18, 2013 at 09:29 PM

    My company is setting up a landing page for a magazine ad and we want to entice customers to fill in a form to get a specific PDF. How do we stop competitors from downloading the document if they use their companies domain. I realize if they use gmail or yahoo it's impossible to catch them. Is it possible to redirect them?

    Thanks for asking.

    Sorry but I don't think we have a solution for that but we have an email validation tool that blocks free emails like yahoo, gmail, hotmail and etc. Here's how:

    You can also use conditions in the email field that would hide the form or submit button when a certain word is entered in the field. This way, they won't be able to submit the form.


    However, if you'd like a more secure validation, you can take your form source code and inject a script that would disallow all their email addresses.
