Youtuber rank is given to people when Jerry and Harry watch and like their videos, it isn't based on subscribers (Though more subscribers does boost your chance of them finding your channel)
You also have to be entertaining and have a lot of your videos on J&H, for example you can't just be someone that always plays hypixel, but wants the rank on J&H for no random reason.
I don't believe this to be correct but I may be wrong. From my understanding it's what @Cheezipoofs said above
But my thought is why would someone that very rarely plays on J&H get the rank? It wouldn't do anything (I'm not saying @Computech88 doesn't play on J&H a lot, I'm just saying that not just anyone can get the rank.)
