Because she willingly became a "public" figure by allowing the radio station to publicize her rush experience -- it's safe to say that she's fair game.

Putting discretion talk aside, all the sororities will know about her. While I can see the sororities wanting to pick her up (hey, it's free publicity, right?)..at the same time I can see them not wanting to do so for the same reason.

That being said, I'm hoping that she does find this thread. I don't know if she really knows what the heck she's getting herself into.
