HN should really stop meddling with headlines until they find people who don’t replace “reservations” with “reserve bookings”.
Reservations is what EVERYBODY calls it. I've made thousands of reservations in my life. I had no clue what a "reserve bookings" is. You can figure it out from context... but why go out of our way to make things so difficult to understand.
It is not “fake reserve bookings” but “fake Reserve bookings” (that is, in longer form, “fake bookings on Reserve”.) As GP pointed out reserve is a proper, not common, noun in this use.
