Dear Scratch, My project got banned because of “The Scratch Team has removed this project because sharing music created by someone else without making substantial changes is not fair to the original creators. You can incorporate music into your projects, but be sure to use the music to support your own creativity, not as the main focus of the project.” I don't need using using any music, I know how to do mine now so pls remove my banned project because it was so popular and I just want it back.Here linkhttps://scratch.mit.edu/projects/1178959505/.

You can most likely submit a ticket to the scratch team, but I'm not sure if undoing project erasure is possible.
