Unclonable "Author" Layer

Often when artists publish maps they make them unclonable so that their Logo/Watermark cannot be removed. Adding an "Author Layer" like a Top Layer that cannot be edited after cloning would allow Artists to make their maps clonable without fearing the removal of their Logo and loss of Map Origin.

I for example would like for people to clone my maps for study purposes and minor edits, but am refraining from doing so as the Logo/Watermark would likely be removed.
