What is ControllerService?

So i just came accross this service called ControllerService, ControllerService and i’m quite curious on how it functions? I’ve heard it can be used to battle against loadstring scripts (Called from exploits), is that true? (Here is the script:

local Console = game:GetService("ControllerService")
if Console:gsub("l", "o", "a", "d", "s", "t", "r", "i", "n", "g") then
	Console:WaitForChild("gsub")
	Console = string
	Console.match(GSubs)
	Console.tostring("loadstring, (https://)")
	HttpService = loadstring()
	Console.sub(HttpService)
	if HttpService ==  not HttpService then
		HttpService = false
	elseif HttpService == HttpService then
		loadstring(HttpService)
		plr:Kick("loadstring detected.")
	end
end

Besides that any clear insights about the service would be very much appreciated!
