Re not reading descriptions:
I'm reading these posts looking for how to block a guest so that they can not instant book with me again. I keep seeing the same response on how to block messages from a guest (nice, but not what I'm looking for), and then one poster says that blocking messages also blocks booking, but then another says that only blocks the guest from sending you a reservation request, does not block them from IB. So I'm back where I started: I have to turn off IB and block messages from specific guests I do not want to host again.
I suspect a lot of the people who keep asking are like me: they want to stop unpleasant guests from being able to IB. There does not seem to be a way to do this. Blocking these guests messages is NOT the answer, they can still make a booking if host has IB turned on. Host is then between a rock and a hard place: either host these undesirable guests again, or cancel them and get penalised.
I've had to turn off IB for this reason, I'd rather miss out on bookings than be forced to re-host someone who gave a bad review that was full of misinformation. One such guest, I had given them a nice review as they seemed OK and left the place in reasonable state, even though they were very needy and kept asking for additional things. Guest review said carpets were dirty and need cleaning. The rooms have hardwood floors with no carpets, so this was complete nonsense. I don't want to get into a fight with these people, I just don't want to host them again, especially as they said they would love to stay again (in spite of the invisible carpet being dirty!).
