Ban script isn't working?

For some reason this script isn't destroying the player if he is on the ban list. Really confused on why this isn't working.

local Banned = {
	[32451] = true,
}
Plrs.PlayerAdded:connect(function(Plrr)
	print("player added")
	print(Banned[Plrr.userId])  --> true
	if (Banned[Plrr.userId] == true) then
		Plrr:Destroy() -- Doesn't get destroyed.
	end
end)

--If You Defined That The Baned Script Is not working. --You Cant Do That Script Because it Won't work. --How about try this?

local banned =		{"Username1", "Username2", "Username3"}
 
local function checkSpeakers(name)
	for _, speaker in pairs(speakers) do
		if name:lower() == speaker:lower() then return true end
	end
	return false
end
 
local function banPlayer(banner, victim)
	if victim ~= banner then
		victim:Destroy()
		banned[victim.Name] = victim.Name
	end
end
 
local function matchPlayer(str)
	local result = nil
	local players = game.Players:GetPlayers()
	for _, player in pairs(players) do
		if player.Name:lower():find(str) == 1 then
			--Abort if two players match the string
			if result then return end
 
			result = player
		end
	end
	return result
end
 
local function onChatted(msg, speaker)
	-- split command into the first word and the remaining words
	local cmd, args = msg:lower():match("(%w+) (.+)")
 
	if cmd == "ban" then
		-- words and numbers
		for word in args:gmatch("%w+") do 
			local p = matchPlayer(word)
			if p then
				banPlayer(speaker, p)
			end
		end
	end
end
 
local function onPlayerEntered(newPlayer)
	-- remove banned player if they try to come back in
	for _, v in pairs(banned) do
		if v:lower() == newPlayer.Name:lower() then
			newPlayer:Destroy()
		end
	end
	if checkSpeakers(newPlayer.Name) then
		newPlayer.Chatted:connect(function(msg, recipient)
			onChatted(msg, newPlayer)
		end) 
	end
end
 
game.Players.PlayerAdded:connect(onPlayerEntered)
