That is really bad. I hope they identify who was behind it so that she might be able to feel secure enough to be free to do what she wants to do. That royally sucks.

I once got a threatening/abusive phonecall due to my making a decision that someone disliked. It was in my capacity as a moderator of an email list I administrate and which I'd cofounded with a friend. Someone got mad at me for restricting a particular user's posting privileges. The guy I'd restricted was not following the charter, and after multiple warnings I finally took away his posting ability and threatened to unsub him. He didn't make the threatening call -- it was someone else.

I just changed to an unlisted number, and there was no prob after that.
