Something similar happened to chouchsurfing. At the beginning it was a small community with a high level of trust and people knew what it was about, and behaved accordingly. Then it grew too much and you find all kind of users, many who just think that's a way to sleep for free and who avoid interaction with their hosts. I guess airbnb will have to adapt (I'm pretty sure they are aware of the problem) and find ways to filter out the bad guys. There's gonna be many more of them as soon as they find out the opportunity.
