There is this girl who is out to get my father and she hates me although I don't understand why. She is threatening to tell everyone something REALLY bad about my father at a Grand Opening party my dad is hosting, by putting flyers on people's cars. That was recently. But before, her and over 10 people that used to be my family's friends, started to talk badly about my father and so I defended him, because he is my father! So then they start to get really rude with me and never leave me or my dad alone. They check all over our Facebook pages, make up fake accounts to add us and add our friends to see what we are doing. It's gotten to a point where I feel like they can find us anywhere. I have some evidence. Would this be enough to sue for harrassment?
