 Roblox is a fun website and game, but there are many creepy mysteries that might have affected everyone's account because of this whole thing. Here are the four, but not five, creepiest mysteries that Roblox might have seen. Number one, Smile. The game Smile is made by a username named Smile. The rumor is that people would get a message from Smile and it would say, I need you here in the game, and if you go to their game, it's just a black screen, but when you turn to the left, you see something. It's a red-faded head with bloody eyes, and when you walk to it, you're gonna feel that the head is going towards you. When you get close to the head, your computer shuts down. When you turn the computer back on, the wallpaper is set to you inside of the game. When you go back to Roblox, you will notice that your account is logged off, and when you log back on, your account gets deleted. Smile was a username made by someone, but it got banned forever. Number two, Melvin. This mystery is one of the most creepiest ones yet. Basically, the rumor is that one person has this issue of, when they join a Roblox game like Phantom Forces, you don't go to Phantom Forces, but you get teleported to a different game. This game, which is a black game with a translucent shaggy near you. You can't close the game until the game crashes. After a short minute, the game crashes and you can close the game. When you go to your inventory, there is a new hat, and it is a translucent shaggy hair, which is called Melvin. There is a user named Melvin, owned by a child named Melvin Blue, was created in 2007. He was a very popular person among other players. He died from cancer in 2008. Roblox made it transparent, ghost type shaggy in his honor named Melvin. The hat was deleted a few moments later for no reason. It isn't known. Some say Melvin got the attention and his ghost was angered. So he takes the life of one child every year. After that, their accounts were deleted. Number three, the April 1, 2012 incident. On April 1, 2012, Roblox was hacked and completely shut down. The rumor is that this hacker had two other accounts that had the same avatar he copied on the user's account which made him get banned. This made the hacker upset and take over Roblox. He first took over the Roblox website and later he took over the Roblox economy. Here are the screenshots that have been taken in Roblox. Here is a forum from a user named Fede, and the forum post was called I'm Back. This message is from a banned user who came back to Roblox. When you look closely to the user, you can see that he is a moderator. This hacker unbanned Fede from the game and made him a moderator. There were many messages that were really bad and inappropriate. The whole catalog was being changed. People were getting rich from this. That later on ended up with a site being completely shut down. Also, in this April Fools hacking, everyone that was banned came back and became a moderator like in the picture. Number four, Vault 8166. This mystery is the most creepy one yet. This game was used to hack GUIs and hide the user's avatar and identity. Vault 8166 was created by hackers. The 8166 number is from a hacker named 1x1x1x1, but the hacker in person did not create the game. The rumor is that it's hidden around the server. Let me tell you the story about this. A user submitted a footage of the hallway of Vault 8166. The recorded data wasn't known. The video shows the hallway full of computer switching codes that contains red flashing lights. There is a strange white room with a poster that says warning, we are watching you. The video starts with the two users walking in the hallway. One of them is fully black, has a particle in it a red fire, and the user's name wasn't known. Unexploiter, his username is hidden. The other user has a head colored in red, and a black torso, the user isn't known. They stopped in the middle of the hallway and looked around, when all of a sudden an unknown figure came running in the middle of nowhere. The two characters started panicking. When the figure attacked, the screen blackens, and the protocol kills them.
