Bun Bun Girls is a group of childish and cringe ROBLOX hackers. In order to know if you have encountered a Bun Bun Girl member, they will have the word "bun" in their username. You can easily avoid them just by not adding anyone with the word "bun" in the name. Even ROBLOX has taken concern into the matter and no normal person can have the username with the word "bun" in it. The Bun Bun Girls have a victim list of Youtubers. However, despite being a hacker who can completely ruin one of the games in ROBLOX, they are quite childish for one. For example, whenever somebody calls their group cringe, they get mad and try to hack that person. Youtubers includeing Kreekcraft have ending up calling these hackers fake!They first appeared in 2021 but as of 2023 they are are returning
Sharkblox: This hacker group is cringe af!
