A family member of mine (older like me) is stalked by someone from high school (who she wasn't even friends with but everyone knew each other because the town was very small). Even though she isn't on FB and lives in a completely other state, he manages to contact her either by coming to the state or sending mail to her home and where she works. He even sent email to her work (and she had changed jobs--how would he know without hours of research? Like Sarah, she no longer stays in touch with anyone from high school). Because of this, where she works no longer has pictures and names of the people working there online. The police can't do anything because he has never made a threat. There are so many ways online to track people now. That's why it's probably best not to give out your name or email on social media. Perhaps I shouldn't have even mentioned what state I am from....
