Sorry to hear this Cindy, you're an inspiration for taking this so well.
Due to certain things in my history which I have only revealed to 3 people on this forum I have extensive experience with Facebook trolls having been targeted myself (not trans related). I know we all have a great deal of respect and affection for Cindy so please don't try to target the person doing this, you may think you're helping but you may inadvertently cause this to escalate.
Just respect Cindy's request, if contacted then report this as a fake account.
Remember the no 1 online rule: Don't feed the trols
