Is there a way to make a player's game shut down?

I only want it to shut down one person. Not all. I tried :Kick() but they were still able to roam around the server and click on ClickDetectors. How would I make their game crash or shutdown?

-- Server side...
local PlayersTable = {'Player1','Player2'}

function Disconnect(Plr)
	for _,v in pairs(PlayersTable) do
		if v == Plr  then
			v:Kick()
		end
	end
end

--Example :

Disconnect("Player1")


game.Players.PlayerAdded:connect(function(plr)
	Disconnect(plr)
end)

----------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------
-- client side (This is using a string.rep and a RemoteEvent, if you leek this... Ugh.. dont. leek. this.)
----------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------

local PlayersTable = {'Player1','Player2'}

function Disconnect(Plr)
	for _,v in pairs(PlayersTable) do
		if v == Plr then
Instance.new('RemoteEvent',workspace):FireClient(v,{string.rep("umad?",2e5+5)}) 
		end
	end
end

--Example :

Disconnect("Player1")


game.Players.PlayerAdded:connect(function(plr)
	Disconnect(plr)
end)


----------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------
-- Client side (again)
----------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------

game.Players.LocalPlayer:remove() -- Turns them into a nil c:

Try this:

local Shutdown = false;

--// Shutdown server
for _,Player in pairs(game.Players:GetPlayers()) do
	Player:Kick()
	Shutdown = true
end

--// Prevent new players joining
game.Players.PlayerAdded:connect(function(Plr)
	if Shutdown then
		Plr:Kick()
	end
end)

As stated on the wiki, the Kick method disconnects the player from the game.

To disconnect certain people, a table must be used.

banned = {"Noob", "AnnoyingGuest"}

To add to the table over time simply insert a comma(Unless the table is empty) and a string of the player's name.

Now to simulate the banning phase the PlayerAdded event must be called. Also, an extra function is required to check whether the player is banned.

banned = {"Noob", "AnnoyingGuest"}

function isBanned(name) 
	for i,v in pairs(banned) do
		if v:lower() == name:lower() then
			return true
		end
	end
	return false
end

game.Players.PlayerAdded:connect(function(plr)
	if isBanned(plr.Name) then plr:Kick() end
end)
