Need Help Completing my ban system. n not working?

I don't know if this works.

local BanPart = Instance.new("Part",game.Workspace)
BanPart.Name = "BanPart"
BanPart.Position = Vector3.new(-198.49, 7.55, -127.81)
BanPart.Anchored = true
BanPart.CanCollide = false
BanPart.Transparency = 1

local BannedPeople = {"YamadaRikkuDev"} -- example person, you can place people's name you don't like.
-- also please use userids as people change their names in roblox

--local DoritosGud = script.Parent:WaitForChild('HumanoidRootPart') --MAKES NO SENSE.
-- put this in serverscriptservice please because this script uses the PlayerAdded function

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(chr)
        wait(.1)
        for i,v in pairs(BannedPeople) do
            if v == player.Name then
                chr:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(BanPart.Position)
                print("You've been banned, " .. player.Name .. "!")
                -- i don't know what to do here, you can replace the teleportation code with the :Kick() function
            end
        end
    end)
end)

If you don't know how this works, let me explain.

The script makes a BanPart in workspace so that the players that are banned will need to go there. Then, it connects a PlayerAdded function in which occurs when a player has joined the game and connects the CharacterAdded function in which occurs when the player's character has loaded in workspace.

If a CharacterAdded function has fired/occurred, the script waits about .1 seconds after the character spawns, checks if the player's in the ban list. If they're one of them, the player will be teleported to a ban part or kicked and the script prints that the player has been banned.

--[[
    Normal Script in ServerScriptService
]]

-- services --
local players = game:GetService("Players")

-- locals -- 
local banned = {
    1, -- roblox
    1361134044, -- notedapi
}

-- script --
local BanPart = Instance.new("Part",game.Workspace)
BanPart.Position = Vector3.new(-198.49, 7.55, -127.81)
BanPart.Anchored = true
BanPart.CanCollide = false
BanPart.Transparency = 2

players.PlayerAdded:Connect(function(player)
    local isbanned = table.find(banned, player.userId) -- you can look on the api about table.find

    if isbanned then
        while wait() do
            if player.Character then
                if player.Character:FindFirstChild("HumanoidRootPart") then
                    player.Character:FindFirstChild("HumanoidRootPart").CFrame = BanPart.CFrame
                end
            end
        end
    end
end)

First of all, you can't set transparency over 1, which is invisible. What I think your DoritosGud variable is the HumanoidRootPart of the Hacker.

So what I would do is:

local BanPart = Instance.new("Part",game.Workspace)

BanPart.Name = "BanPart"

BanPart.Position = Vector3.new(-198.49, 7.55, -127.81)

BanPart.Anchored = true

BanPart.CanCollide = false

BanPart.Transparency = 2

local HaxPerson = {"malachiRashee"}


wait(2)

game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(char)

for i,v in pairs(HaxPerson) do
if player.Name == v then
local DoritosGud =char:WaitForChild('HumanoidRootPart') 
    while true do

        wait()

        DoritosGud.Position = BanPart.Position

end
end
end
end)
end)
