This is because ROBLOX wants their audience to be child-friendly for an clean and fun experience. While, yes, many words that aren't supposed to be censored ARE censored, ROBLOX is aimed for 4-14 years old, and most of them could be saying bad words on chats if the censor system wasn't implemented.
