Behavioral analysis (the thing he's talking about) doesn't work that well and has a hard precision limit due to the nature of online gaming. What the player sees, what the server sees, and what other players see are entirely different things. I'm not even talking about plausibly deniable things like visual sound location. Nobody's using complicated stuff like this in practice though, as there are easier methods. But of course this path can be taken, and it's not possible to block easily.
