Anti Exploit Scripting and more?

I dought there is a sure fire way to prevent it, but is there any type of script that could prevent speed hackers? My game occasionly will get exploited that's why I am asking.

Here is a script made by Merely that kicks speedhackers:

local Player = game.Players.LocalPlayer
while wait(0.5) do
	if Workspace:GetRealPhysicsFPS() > 61 then
		Player:Kick()
	end
end
