How to avoid the theft of your mapping?

[HarmonyXDXD]

I don't know very well in which section of the forum this goes

I wanted to know if there is any way to register a map as your own and prevent its use without your permission.

The problem is that I made a map for a user of a role server and the administration has used it in other maps of the same server

then, the administration defends that the maps uploaded to the server are of free use for the administration
