I put the module script in the ServerScriptService and that module script is the main function of my game, and I put normal script in the Workspace which can use function from the Module script so exploiter cant see them and they didnt copy anything from the game.
If they copy your game, they can see the script instance but they won’t be able to read the source code. AFAIK, no script decompilers can, not even with remote events/functions.
an exploiter can only coppy client sides stuff and only compile module scripts and local script that are not in ServerScriptService or ServerStorage
if u use a normal script and its not gonna be a problem for game balance that he removes the script on the client then it gonna be fine
