My question involves defamation in the state of: California
My gf is being harassed via email and myspace. She will not leave her alone. For the past 2 years they have been on and off "friends". My gf simply being nice to my ex wife because we have a child together. My ex started trashing me and my gf told her not to contact her again. She kept doing so via myspace, and saying nasty things about her. My gf did respond childishly at times, once making a fake account and posting a pic of her photoshopping it and making her look weird etc. She deleted everything months ago and we have simply been ignoring her. My ex started sending her messages again on myspace and when I asked her to stop she said she would "email that b*tch anytime she da*n well felt". My gf was advised to get a restraining order but it worried that somehow she will get proof it was her that made a fake account and get into trouble. It's all dumb and petty yes. But my gf has made no contact with my ex in months, and my ex contines to write her everyday.
Should she go through with this restraining order? Or can we send a cease and desist letter asking her to stop contacting her? or do we need a lawyer to do that?
