So how would they help this person? Reimburse her? AirBnb is technically not liable for those damages right? So how much do they give her? If it's too little it might be insulting. Too much and people would still complain about irreparable emotional damage.

They said they're trying to help catch the perpetrator right? In my eyes that's all they really can do and the only thing that matters. The damages are primarily the girl's responsibility but the criminal is partially Airbnb's fault.
