Kinda relevant: Here's a thread about a group of aircraft flying in the U.S. that were trying to hide their identities by using the FAA's "Privacy ICAO Address" (PIA) program. Under the PIA program, aircraft can broadcast ADS-B but they don't use their real registration info, so theoretically you're not supposed to be able to tie the aircraft to a person or company: https://twitter.com/lemonodor/status/1456377882582798338 https://twitter.com/lemonodor/status/1456377882582798338 But because it's still relatively rare for aircraft to use PIA, and even more rare for a group of several aircraft to use PIA and take off from the same airport and fly together, they attracted the attention of a few people on twitter who suddenly got very interested in these aircraft and who was flying them. People quickly figured out where the aircraft where flying to, and realized that airport had a public webcam. As the jets landed, people confirmed the tail numbers of these aircraft that were trying to fly under the radar, so to speak. The thread ends with the identity of the aircraft and their owner having been discovered, some hypotheses about the reason for the flight, figuring out which resort the passengers were staying at, and... the airport having apparently seen what was happening on twitter and sending someone out to put a plastic bag or something over the webcam to block everyone's view.
