Well the US Congress is considering creating a new branch of the military to control outer space assets. I believe some satellites can monitor anything wireless and/or control a dedicated sensor near a target. Not sure I would want to piss them off. I don't think you can be anonymous & obnoxious at the same time. Spacex is making space access easy, fast and cheap. The moral of the story is "don't post it on the international network".
