Roblox deleted the Billy character mainly due to issues with its hitbox, which was smaller than other characters. This smaller hitbox let players exploit the game by making their avatars appear headless when using Billy.
Players found this exploit unfair, as it gave them an advantage over others. The hitbox issue allowed them to avoid detection and gain an upper hand in gameplay.
Another reason for Billy’s removal was its thin design. Some users believe this design contributed to the character’s deletion, as it made the hitbox problem worse.
Roblox aims to ensure fair play and a balanced gaming experience. By deleting Billy, they addressed the exploit and worked towards maintaining a level playing field for all players.
