Very simple and fast.
Source Code:

-- Services
local DataStoreService = game:GetService("DataStoreService")
local Players = game:GetService("Players")

-- DataStore
local BanDataStore = DataStoreService:GetDataStore("BanDataStore")

-- Admin UserIDs
local adminUserIds = {
	4340466686
}

-- Function to check if a player is an admin
local function isAdmin(player)
	for _, userId in ipairs(adminUserIds) do
		if player.UserId == userId then
			return true
		end
	end
	return false
end

-- Function to ban a player by username
local function banPlayerByUsername(admin, usernameToBan)
	if isAdmin(admin) then
		local success, userIdToBan = pcall(function()
			return Players:GetUserIdFromNameAsync(usernameToBan)
		end)

		if success and userIdToBan then
			-- Set the ban in the DataStore using the user ID
			local banSuccess, banErr = pcall(function()
				BanDataStore:SetAsync(tostring(userIdToBan), true)
			end)

			if banSuccess then
				print(usernameToBan .. " (User ID " .. userIdToBan .. ") has been banned by " .. admin.Name)
				-- Optionally kick the player if they are currently in the game
				for _, player in pairs(Players:GetPlayers()) do
					if player.Name == usernameToBan then
						player:Kick("You have been banned from this game.")
						break
					end
				end
			else
				warn("Error setting ban data: " .. banErr)
			end
		else
			admin:SendNotification("Notification", "User not found or error retrieving User ID.", 5)
		end
	else
		admin:SendNotification("Notification", "You can't use this", 5)
	end
end

-- Command listener for the /ban command
Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(message)
		local args = message:split(" ") -- Split the message into parts
		if args[1] == "/ban" and args[2] then
			banPlayerByUsername(player, args[2])
		end
	end)
end)

-- Check for bans on player join
Players.PlayerAdded:Connect(function(player)
	local success, isBanned = pcall(function()
		return BanDataStore:GetAsync(tostring(player.UserId))
	end)

	if success and isBanned then
		player:Kick("You are banned from this game.")
	elseif not success then
		warn("Error retrieving ban data for player: " .. player.Name)
	end
end)

I think you are just dumping a script instead of explaining how it’s supposed to be used
