If someone decided to meticulously track everything I do. Follow me wherever I went. Put a GPS tracker on my car to see everywhere I visit. Peep inside my windows to see what websites I browse. Look over my shoulder at the grocery store to see what items I buy. I would consider that stalking and attempt to file a restraining order against that person. Can I file a restraining order against Facebook? Or Google?
