You put a whole shitton of details about your life into a computer system. Even if accessible only by your "friends", it is still trivial to socially engineer your way into any non-celebrities friends list and steal this information.
Your only defence is that no-one cares about you enough to do it. Also, please sage your posts so as not to bring shitposting to the attention of the more sensitive and easily-upset members of the board,
