I haven't use AirBnB before, but I do use CouchSurfing a lot. CouchSurfing's system of verification, vouching and references makes a big difference to how much you feel you can trust someone who asks to use your home. I do still sometimes accept guests with no references, particularly if it's a last minute, but I check their IDs first, and only give them limited access to my home.
