My AntiBan wont work for my Admin Commands?

I am trying to make an AntiBan for my Admin Commands, however it does not work..

Here is what I currently have

AntiBan = false

if Msg:lower() == Main.Bet .. "antiban" then
                if not AntiBan then
                AntiBan = true
                if AntiBan then
                repeat wait()
                local H = Instance.new("Hint", game.Workspace)
                if Plr == nil then
                H.Text = Plr.Name .. " has either left the game with AntiBan true, or has been kicked or                banned. The server will now shutdown..."
                wait(3)
                for i,v in pairs(game:GetService("Players"):GetPlayers()) do
                    v:Kick("Please do not ban or kick an Cryptoin admin!")
                end
                end 
                until not AntiBan
                end
                end
                end

Please help, I have tried multiple things.
