@Jasmina17 What we as hosts would like to see as far as guests having to be subject to some evaluations like we are, will never be implemented by Airbnb. Their interest is in removing impediments to booking for guests, not giving hosts more tools with which to vet prospective guests.
First they remove our ability to see profile photos before accepting, then they bury our house rules at the very bottom of our listing where guests will not scroll down to, then they change the "pre-booking message" to post booking, now they put a heading over the house rules called "Things to keep in mind", as if the rules aren't all that important.
The company's entire focus is on having bookings roll in as fast and furiously as possible and they will do whatever they can think of to facilitate that.
