Could you make an option in the save creator thing that says "no copy" and when you turn it on other people can't Ctrl+X, Ctrl+C or S in that save? Also you can't upload the save when you have it open.

@TheCombustionChamber(View Post) The game is open source, anyone can just compile a version that has copy and paste allowed. That or they can use a modded or previous version.
