I came across a Facebook app/tab for a brand that required that the person *Like* the brand before being able to submit the form. I'm used to normal "like-gates" in which a splash screen is shown saying you have to *Like* the brand before being allowed to fill out the form. However, in this specific case, the Like button was "step 4" on this particular form that didn't have a Like-gate.

Here's an example of the form:

This seems to go against some of the [Like button guidelines](https://www.facebook.com/brandpermissions/logos.php); however, does anyone have any feedback on if this is 1) allowed and 2) something that is a good practice? 

I have my personal thoughts on this practice; however, I am curious to know if anyone has any data or experience with this type of layout.
