Given this new "Mandatory Grace Period" Airbnb should delay sending contact info out for 48 hours, and introduce a manual send button (see below).
This new directive is a gift for anyone looking to amass data. And it's not as if Airbnb is immune to abusers and data scrapers.
This "Book, Get Info, Cancel" exposes the host by releasing private information to possible bad actors.
I had already made a suggestion to prevent host information from being automatically sent out for an IB booking. I believe it was archived as a no-go.
The suggestion was to have a choice:
1. Automatically send on confirmed booking.
2. Click button to manually send, i.e. when I want to send it.
Unless Airbnb wants to employ hosts instead of the no responsibility, no risk "freelance" status, hosts should have some control over their listings and who gets their information.
Airbnb cannot have their cake , and eat the hosts cake, and share the hosts cake among guests.
