Some questions about the demo

Hello!
I am new to CodeCanyon and I am almost ready to submit my first item. I built a subscription based video platform (similar to platforms like Netflix). The question is, can I disable some features from the demo of my application? I can’t afford paying huge bills to Amazon S3 for huge files that someone might upload and I don’t want people to delete staging content that I uploaded for display.

Thank you a lot!

You should have some kind of demo mode which will prevent people from messing up your demo site.
