I am being as honest as I could possibly be about our services there are no twists to it. If you are to buy an UNLIMITED package then you are able to go as far as you wish with it. There is of course going to be rules and guidelines on what to and what not to upload on your site that is illegal.
As i'm being honest with what I have said, no limitations on how much you want to upload. If the package is listed as unlimited, go ahead and use what you wish. The only thing is, 50,000,000GB? That won't even get hit. And using that amount of GB with any hosting service your site wouldn't even run fast and smoothly. So we would only see such method of that as trying to crash our services, therefore we would deactive your services until we have spoke to the customer about the situation.
So yes as I said anyhow, once we release every bit of information you need to know will be on the site, otherwise you can hit an agent up on live chat.
