Backpack detection not working anymore?

So, I used this about 2 years ago and it worked, but it doesn't work anymore (Detecting if someone inserts comething into their Backpack.

while wait() do
	if game.Players.LocalPlayer.Backpack:ChildAdded() then
		game.Players.LocalPlayer:Kick("Exploits detected.")
	end
end

This event will activate when player inserts something into Backpack

game.Players.LocalPlayer.Backpack.ChildAdded:connect(function()
	game.Players.LocalPlayer:Kick("Exploits detected.")
end)
