This sounds fishy- it's an inquiry for a month:
"Though I have been a verified AirBnb user for years, this is my new account because I got my phone, cards, and passport stolen while traveling across Europe. Due to two-step verification and the like, I was locked out of my email (which is tied to my previous AirBnb account). I understand the risk you are taking as a host, so I am happy to include my fiancé’s Airbnb account if that will help."
He then asks if I will lower the price by about 30%.
Has anyone encountered this sort of message?
