I assume your banlist is in a datastore?
Write a script to remove yourself from the list.
Not sure on your configuration, but you should be able to also rewrite the banlist check function to ignore you.
Usually we could have helped you. But since this is a datastore and WE dont know how you store data in Datastores. I can suggest a simple fix though… you will need to change how you make keys.
If your key is like this :
"UserOrWhatEverPrefixYouPutHere"..player.UserId
--or
player.UserId.."Whatever suffix u put here"
Change the prefix/suffix (or both) to something else.
This is in the wrong category and do you really expect to profit from reuploading a game which you ripped the map from? Pretty petty trying to do so in the first place.
