Join 7HZA on Roblox and explore together!True story: I was waiting online at a museum exhibit, when I was bored and decided to make a Roblox user for fun. I noticed that the 4 character username '7HZA' was available, so I decided to take it. As I created the account, it managed to land on an ID with repeating digits. Isn't that cool.
