@Kim2998 Are you aware that profile photos are hidden from hosts until after a booking is confirmed? All you will see at the request stage is a circle with a letter in it in place of the profile photo.
There isn't anything sketchy about a new profile with no reviews. Everyone has to start somewhere. While your profile isn't new, it once was and you also had no reviews. Were you sketchy?
You just have to be cautious with a request from a newbie. They may not really understand how Airbnb works, they may not have bothered to thoroughly read your listing info, including the house rules, they may think they can book for 1 and show up with 7. So a host has to be more vigilant, communicate more, ask questions, ascertain that they have read through everything and will comply with your rules, etc., than you would with an experienced guest with lots of good reviews who communicates well.
What kind of message accompanied the request?
