1x1x1x1

1x1x1x1
1x1x1x1 was an account created by Shedletsky on May 25, 2010. It was primarily used for testing exploits In RC7. Although the rumors about 1x1x1x1 have long since been debunked, many Robloxians continue to hold onto the belief that, like with John and Jane Doe, it is owned by a hacker. Though the account is inactive, many players speculated that he became active again after Roblox released updates to character customization, which further increased fears that "1x1x1x1 is back and will hack everyone". Many hackers and game exploiters frequently claim to be 1x1x1x1. With 1x1x1x1's popularity within the game, the character has been made into a Roblox toy, though unlike other toys in the series, 1x1x1x1's toy appearance does not match his Roblox avatar.

Why is he famous but scary
1x1x1x1 was used to prey on fear in one of the stories created by Shedletsky, mentioning an "evil 1x1x1x1 part" and as such many people have speculated he is a real hacker. However, former administrator MrDoomBringer verified that 1x1x1x1 is not a hacker and started as part of one of Roblox's backstories created by Shedletsky.
