ok lets say a grown up woman (27) has the power to financially fuck you up and does so - you could maybe go after her legally, but it would cost you even more money and it wouldn't be guaranteed that you would get any of it back

this woman is obviously a total bitch
you have her full name, her work address, linkedin, phone number and potentially (but not sure) her private address

what could one do, to make her life temporary a little less enjoyable, without hurting her?

I don't want you as my personal army, I just would like ideas
