This is my code:

function FilterString(str)
	local filtered = game:GetService("Chat"):FilterStringForBroadcast(str,game.Players:GetPlayers()[1])
	if filtered ~= nil then
	return filtered
	end
	return "< Filter Failed >"
end
local sources = {
	"TextLabel",
	"Message",
	"Hint",
	"StringValue"
}
game.DescendantAdded:connect(function(desc)
	local long = desc:GetFullName()
	if long:find("Chat.Frame.ChatChannelParentFrame") ~= nil then
		return nil
	end
	print("got " .. desc.Name .. " from " .. long)
	if desc:IsA("TextLabel") then
		desc.Text = FilterString(desc.Text)
	elseif desc:IsA("TextButton") then
		desc.Text = FilterString(desc.Text)
	elseif desc:IsA("Message") then
		desc.Text = FilterString(desc.Text)
	elseif desc:IsA("Hint") then
		desc.Text = FilterString(desc.Text)
	elseif desc:FindFirstChild("Humanoid") then
		desc.Parent.Name = FilterString(desc.Parent.Name)
	else
		print(desc.Name .. " does not need to be filtered")
	end
end)

It should filter anything with text, but it doesn't work.
