Yeah. In Hollywood it could be. In fact, many times I get confused which one os official upload. And they have so many version of trailer, it is quite confusing there. Especially, in Bollywood, for most of big production house, you can unofficially upload their trailer like YRF, Dharma, Red Chilli. They will instantly block your video as their main focus is to brake the records, Hollywood doesn't have such things and it's great as they foucs more on penetration, it doesn't matter to them from where it is coming.
