Booking.com is not protecting your data and is giving your personal information/contacts to scammers. I have been the victim of a scam for the first time 2 days ago. I had a reservation for an apartment in Manchester and I trusted the "host" who contacted me via booking.com to block the money from my card. He had all my info and he even confirmed the reservation number. Booking.com should be vetting every property that is listed on the platform but this is not the case, your personal data are not in safe hands and you could be the next person to be scammed. I USED BOOKING.COM DOZENS OF TIMES BUT I WILL NEVER USE IT AGAIN!
