This answer is based off your topic, there is not much to manipulate if you try hard enough there can be but they can only really get to the Physics RemoteEvents and RemoteFunctions by watching them in local scripts and then abusing them (see above answer link for more detailed explanation)
So, my game has been abused by exploiters, i’ve found out it was network ownership so i patched it, the next day i try to see if there was any exploiters and i saw a couple of them doing ReAnimations or whatever they call them, tried to set it so every 20 seconds it sets every part’s network to nil, unanchored control scripts are fixed but im talking about the reanimations.
