It's great that you've gotten off to a good start, but that's Airbnb's greatest strength. They generate bookings. That's one thing you can depend on.
Unfortunately, everything else is rather chaotic and unpredictable. And there's these scams.. Heavily lopsided victimizing the host, rather than the guest. Airbnb will always favour the guest in any ruling, so it's best to avoid Airbnb involvement, if possible
My mantra is to involve Airbnb as little as possible, because the risks of Airbnb intervention are too high.
Deal directly with the guest wherever possible. Getting Airbnb involved can really have negative effect on you.
Airbnb realistically delivers only a few things:
Bookings
Payments
Reviews
That's all you can expect, and aside from that, it's best to keep them out of everything else.
I hope that helps...
