Would a "don't allow others to export my information" feature, maybe with some granularity, help with this? So if your friend dumped their info to leave, or sent it directly to another app or service, you wouldn't be included* since you opted out of allowing others to export you? * or, with some granularity and tuning controls, maybe for example just your name and it's presence in photo tags from your friends library, and nothing else, would be included.
