I really hope this incident doesn't break her spirit. As someone who's been shot at, beat up, robbed, held up, and still trusts people: What doesn't kill you makes you stronger.
That said, I also rent out my place through AirBnB. (http://www.airbnb.com/rooms/106355) I interview everyone who stays with me through Skype before confirming any reservation. AirBnB, has a very classy membership, and we've had great experiences with all our guests, but due diligence is still a must. Communicating with your potential guests is essential, as is reading between the lines. You should also make an effort to look at their face at least once before booking. Skype is perfect for this and AirBnB doesn't block it.
