@Oran369 What a weird, convoluted situation. It seems to me that this Bartheme needs to deal with Airbnb and tell them someone who he helped with some translation has used his photo and his name to set up an account and is making fraudulent bookings under a fraudulent profile. If he doesn't know how to do this, maybe you can help him.
The thing about dealing with Airbnb CS is that you can't go on long, convoluted explanations. You have to keep it as simple as possible.
If I were this person who has had his name and photo stolen, I would contact Airbnb by message, not phone, and write like this:
"TRUST AND SAFETY ISSUE
A person who employed me for some translation work, Scott, opened an Airbnb account using my name and my photo.
I do not have any access to that account, as it was set up by this other person, Scott, without my knowledge, until a host who had a problematic booking from this Scott person alerted me to the fraud.
I have never had an Airbnb account before and I did not set up that account, which uses my name and photo. This is fraud.
Please advise me if you require more information regarding this cybercrime. This is a fraudulent account that needs to be shut down and investigated. Another person cannot use my name and photo to open an account, it's illegal.
I await your reply"
Now, I'm not sure how B. can send a message to Airbnb if he can't get into that account. He may need to set up a new account in order to talk to Airbnb.
