@Taylor317 It's hard to comment on this situation without knowing the full story. If there is an ongoing legal dispute, it's understandable that you or your friend may not want to comment in this very public forum on the nature of the alleged security breach. But it's clear that Airbnb takes it seriously enough to take the unusual step of terminating the entire account rather than suspending the listing. I'm not prepared to take a position on Airbnb's actions without any information on the reasons behind them. Does your friend even have a guess at what she's been accused of?
On to the less sensitive topic - what payments do you consider to be what Airbnb owes this host? Are you talking about completed, past reservations (excluding the one quoted in the termination notice) that haven't been paid out yet? Or specifically the disputed booking? Or also an outstanding damage claim? Or the future bookings that Airbnb unilaterally cancelled? There are separate policies in place for all of those different scenarios in the event that an account is terminated, and nothing in your account provides any indication of which would apply.
