How can can I keep guests who aren't verified from instant booking with me? I checked the 'Guests who meet my requirements' box which was recommanded by Airbnb but I don't know what that means or covers. I like instant book because I think I may be getting more bookings that way.
If you have ticked all of the boxes regarding verification and good reviews from other hosts, then that's it.
It's not clear if you mean you don't know what verification means? If that is the case what it means is they have offered some proof to AirBnB that they are who they say they are. It's not a background check, etc..
