She's very vicious as we have seen when she contacted Challengeseekers Family/ sister to get them to bring quin back to the states against her will.
She's wanted to get in contact with two other members here to dox you and quite frankly the way she's threaten to have something happen to you and then say that you both lived in the same state is terrifying. She hates you because of past interactions that she still is unable to let go and that just screams motivation.
I urge you to at least start a report with police should anything further happen there's a file started.
