There's really no way to get caught doing something like this if you're on the same LAN as everyone else as long as your computer's name isn't anything that personally identifies you.

I know that this can be prevented, but if they use your local address and the fact you're connected to their network to get information about your device, you're a little bit fucked unless someone else has the same device as you. And even then, I'm almost 100% sure that they can squeeze enough information to pinpoint your exact device.
Just saying.
