If you mean a guest who contacts you via Airbnb and then you direct them off the platform to avoid cost then I guess they would close you down,
How can they stop you from accepting bookings from other platforms?
Also you might get returning guest who want to book direct with you,
Personally I have stopped taking direct bookings they have been the one who let you down, cancelling at last minute,
Remember you have no cover at least with airbnb you can set your cancellation to strict,
