My account was hacked two days ago, and all my calendars were unlinked, allowing 3 instant bookings, all of which were bogus. I called one of the people and she said she had not booked anything with me.
When I investigated in my Airbnb account payout method, the hackers had added a PayPal account as the default for payouts, and my last real payout, plus one of the bogus ones, went to that hacker's account.
I have opened a ticket with Airbnb to get my money from the rental that arrived this past Tuesday which went into the hacker's PayPal account. I hope they send it soon because I was counting on that $2400!!
I have since changed my password, and removed the hacker's PayPal account from my payout methods. Let's hope that stops them from doing it again!
