E.g., if I know someone has put a hold on their mail delivery for a week, they are likely going to be on a trip and their house empty… Take that example and think about instant messages and emails sent and received from family, friends, employer, etc. One sees how an app like TikTok can hoover up information tangential to people in classified/sensitive government and military jobs. (Not to mention industrial espionage).
