Booking.com violates everyday the right of answer concerning guests reviews on Hotels. This means that comments can be made to the hotel, no matter what they say, that they won't be removed and answering will not be possible. Also fraud is possible, because hotel owners can make reservations on similar hotels just to make bad reviews and improve their own competitive conditions. Booking.com doesn't care about the hotels that they sell, no matter how stupid and unfair comments are. Maybe hoteliers would do better business in investing in Adwords Google campaigns directly instead of giving a commission to Booking.com
