I wouldn't be worried at all about them tracking you down afterward -- only about the hassle the crew could give you during the rest of the flight and/or at the arrival station. Getting kinda off-topic, though; I wasn't sure I was 100% serious when I first brought up that photo/video might make a nervous FA retaliate to try to shut it down.
