c00lkidd (not to be confused with 1x1x1x1), is a Roblox hacker from 2013. Even though he joined in 2013, Roblox made a study that c00lkidd had a different account before 2013, he just got perm-banned. c00lkidd was pled not guilty. Builderman (a.k.a the co founder of Roblox), said that he might hack other popular games like Brookhaven, Adopt Me, or Livetopia.
