@John7822 I assume you requested a booking rather than actually booking these places. It will damage the host if they continually reject requests and they will be fined if they actually cancel a booking. Perhaps better to use the Instant Book filter as this will remove the need for the host to accept the booking.
My other advice is to stick to the 'non corporate' hosts who actually rent their own places. Mega hosts are loved by Airbnb for the revenue they bring in but they have no real skin in the game and tend to give a lesser more impersonal service.
Given that many hosts also list on VRBO (especially the big ones) your plan to avoid these hosts by using VRBO is somewhat flawed.
