I agree here too, being aware she might be sprung on me in person somewhere is helpful. However, my panic anxiety doesn't always dictate how I will physically react.
I still think I'm smarter to stay away from a possible scenario where she could show up.
I also have taken a few steps to privately warn some of the members in my group about her and what she could say.... kinda like pre-damage control.
She used to be really good at making me crazy, and so help me, I don't want to let her do it again.
