There are several options, depending on how much effort you wish to make. First off, you can try to engage the person who has done the booking, and ask them to supply more information, or even better, ask them to have the people who will be staying create their own account. This will take some time, and may or may not be succesful.
If this was an IB booking, you can simply call AirBNB and say you are not comfortable with this booking and want them to cancel for you.
If this wasn't an IB booking, then you can find the clause in the TOS which forbids third-party bookings and then call AirBNB and make the point that this booking is against their own TOS and you want the to cancel for you.
Good luck!
