I don't have first-hand experience, but I own a couple of short-term rentals, and the word on the street in the hosts community is that booking.com (BDC) is full of scammers and not worth the effort to integrate with.
This makes me wonder where you get your word from? Booking is well established since a very long time, if a host is problematic you'll see it in the reviews. If they're scams they get removed from booking. For clients there is no way for them to scam a host.
