Hi @William-and-Mary0
I have to say I am a little confused by your post.
You can set your listing so only verified guests (those with photo ID such as a passport can book).
Hopefully you don't have instant book turned on.
If you don't you will get a booking request come through. If the guest doesn't have a photo (as you don't !) or information (as you don't) on their profile - simply ask them for some background about themselves.
I normally ask them to tell me a little about themselves, their plans for their stay and why they chose my place.
This will help you make a judgement call as to whether you want to accept them.
Third party guests aren't allowed to book unless it is an approved business profile.
If someone trys to book on behalf of someone else you can decline their booking.
I would recommend you have a photo on your profile and complete some information about yourselves and why you host. Just as we hosts look for completed profiles as a trust sign - so do guests.
