@Costas11 What you have to understand is that an Inquiry is just people asking questions. They may have sent out 10 Inquiries for the same dates to 10 different hosts. Even when you answer all their questions, send them a nice message, many of those people won't even bother to message back thanking you for your time, so there is no point in blocking off dates for them. If you blocked the dates, someone who was actually serious about booking wouldn't be able to book those dates, meanwhile you're waiting to hear back from someone who may never contact you again.
There might be some situations where you'd want to block- I've done it once. This was because a guest had sent an Inquiry, we ended up messaging back and forth a few times and I really liked her and wanted her as a guest. She said she needed to book a flight and then she'd get back to me. I didn't hear back from her for about 10 days, then messaged her again to ask if she was still planning on coming, as if I got a Booking Request for those dates, I'd have to accept it. She right away messaged back, said yes, she was still wanting to come but has a fear of flying so had been procrastinating booking the flight. She said she'd book the flight that day and get back to me, so I blocked the dates for half a day and she let me know her flight was booked, then I unblocked the dates so she could book them right away.
