Is there a way to make the `loadstring()()` Unexploitable?

Technically there is a way, however roblox being it's already loaded coded methods and functions and events cannot accept the outreach administration tools it would allow you. As you can see if you wanted to fix loadstring you'd have to have robloxes permission as they have locked coded items so hackers cannot break others stuff, but this also causes an issue since you cannot fix items in your game, you also don't have 100% control of it either. Roblox is a great game making game, however the developers are in a locked rule cage and have some room, however they are locked in rules that doesn't allow them to reach full potential for their game. However if you disabled the loadstring in ScriptService you can prevent hackers from using it. Then you'd just have to use other items to script. Good luck! Hope my nonsense didn't make no sense...
