I posted an example above but instant book doesn't force a potential renter to be screened which makes it easier for destructive guests to book. If you're throwing a party, would you rather instant book or have to chat with the host?

As my example, if a renter instant books and is going to bring 40 people to a place you are legally approved locally for sleeping 14, other neighbors can report you to the city and you could be fined or lose your license to rent.

So you can have issues with instant bookers even if they aren't destructive.
