As for "uberl33t undetectable hacks", there really isn't such a thing... anyone who knows what he's looking for can spot cheating by using spectator mode. This applies to pretty much any kind of hack, because cheating players behave differently from non-cheating players (main things to watch for: they react to information they shouldn't have, they can have more ammo than they should have, and they play at a level way higher than what you would expect).

I think the real problem with hacks is that they can disrupt public servers and the like: while you can usually deal with cheaters in a highly monitored, private server, it's not so easy to do that in a public game (or a private game with a full server, for that matter).
