She has active identities here and there is a tell here and there. I think you should go to your facebook settings and reset some privacy bars. You can make it so that you will not get friend requests and hide your own. By simply changing some settings, you can eliminate a lot of the harrassment. I would not have my pictures or posts set to public where anybody other than friends could see them. You really should look into some sort of legal action if possible if you cannot ignore her. She has certainly showed a majorly creepy side here and is more manipulative than some think. She has likely earned the trust of posters here for info via PM exchanges only to use that information to split people.
When you see a poster rocking the boat here, it could be her. But she is not above having other id's to talk smack about her own fake profiles hoping to earn trust for certain handles. She has multiple personalities and slips at times when triggered or her opinions pressed and seemingly has moved on to acting like men as well. People who share personal information here do so at their own peril. I learned that and found out the person I had issues with was in fact her. I could share more, but she learns as she goes and will alter her manipulation if too much is said. VPN's allow her to constantly come back and there is little VC can do. She is definitely hung up on many people and things here. Lastly, she has made your info public, so perhaps doxing her is fair game as well. You have been close to her or allowed her in so to speak, so you have more info than any of us Jess.
