Those are far less spoofable because so much of the information comes in the form of un-spoofable things like echo delays and directional information.

You could spoof Mode C altitude, of course. You could spoof a distance from the radar that's more than what your actual distance is by delaying your response to the interrogation. But that's about it. You can't spoof direction, and you can't pretend to be closer than you really are. I'm sure you could still make a minor nuisance of yourself, but it's not going to be a very big deal, I'd think.

I think you'd have to either be very close to the radar or airborne to pull any of this off, too, which means that you likely get to play games only once, then the large men in black suits will come ask you to please stop.

They may even omit the 'please'.
