This seems to be more a hobby project. There is no money being asked for working somewhere, and from what I can tell they don't deal with 'what happens with bad guests' at all. It's more like couchsurfing.org or Craigslist - 'hey there are all these people who want to meet for some reason or another, we are just a messaging service, good luck afterwards'. Which is fine for some purposes of course, not dismissing the idea.
