This video was an April Fools joke that Think played on his subscribers. In the video, Club Penguin has banned Think because he was crashing servers, forcing him to rename himself as 7h1nkno0d1es. In the end Think explains that this video was a joke. This video scared many subs.
Apart from this video, Think never uses this username. So if you see a "7h1nkno0d1es" running around on Club Penguin or anywhere else, remember that it's not him.
