PLEASE HELP! How do I search for a specific guest’s profile and reviews on Airbnb?

Hello! How do I search for a specific Airbnb guest?

I'd like to see all of the reviews that a guest has left for hosts they've stayed with before. I'd also like to see all of the reviews a guest has gotten from hosts in the past. At the moment, it's hard for me to use Google to look for a specific guest. Airbnb's robot.txt file I think is making it hard to search for specific users: https://www.airbnb.com/robots.txt
