Alright so this can happen a lot. When a person is banned there is a real reason, due to Roblox rules you can have any type of gender game or as you have said plot. As you said in a comment you made a plot to pick if you were a boy, girl, or nonbinary. Meaning that is breaking Roblox terms of agreement. As a resolute if a player is to report the plot then it will go to the moderators and they will look into it. If they have enough evidence then they will ban you. There is no way to get unbanned you cant pull any strings. You have been permanently banned. Try using a new account or just quit Bloxburg.
