Is this a legal loophole in obtaining Premium membership to Youtube?

I think a person can have multiple Google accounts. This means that the same person can create a new Gmail account every month just to be able to continue accessing the free premium Youtube subscription for a month. Is it in a sense a "legal loophole" that someone can exploit?

Just to clarify, this is not something I want to do. It's just a question that comes to my mind and I want to know the answer.
