Free premuim

So, I wanted to make a HWW game(to play as USA), but im broke and didn't want to stay up all night for a chance to. So i hit up the youtube video i normally use(it has a link in the discription, COW sponsored it so you can get two months of premuim and 20,000 gold if you make a new account). But when I made the new account, I saw it ends in December... 2026. So i just got a year of premuim on an old sponsored youtube video that shouldn't work. Take advantage of this before it gets patched.
