My PayPal account was charged over £669 on September 3rd, 2016 by Airbnb: £422 from my bank account and £247 from the backup credit card listed on my PayPal account. I was not a guest and I had not booked or tried to book anything via Airbnb, but they still charged me. Fortunately, I had set up the PayPal email warning system to tell me every time my account is used and my husband noticed the warning. I have never used Airbnb or had anything to do with them, having seen all the reports in the UK press about the horror stories. I did not lose anything, as the charges were eventually reversed. However, there have been no details from PayPal about how this could have happened. I have emailed them several times asking how it was possible Airbnb could apply charges to my account. So far, all I’ve heard is silence and a load of standard emails telling me they are always trying to improve their security systems. My opinion: they’re not good enough.
