I would think they would have told you what additional infor they need when they rejected you.

Without seeing the app and the answers it's kinda hard to say, but there is a zero dollar trial membership available to both uys AND girls that can be verified (referenced) by an existing member, so off the top of my head I'd say to ask if any of your clients or an escort you know is a member there already. If they are ask one of them to reference you.
