Do changes to reservations not have to go through AirBnB already? I feel like they should already be able to audit accounts that change reservation details often.

Changes can be made through the Airbnb website. But, apparently that's not required.
FWIW, the only contact I've ever had from hosts outside the system is emails (which I believe were actually relayed from Airbnb, not sure) and actual in-person contact upon arrival (75% of the time, the host has met me for check-in to hand-off keys, answer questions, and show me any oddities in the home).
