@Emilia42 Holy s!*#, I didn't know this.... then again, I've never cancelled on a guest - I've always convinced THEM to cancel on their end in the middle of their stay if there are too many rule violations. I always assumed that if the host is the one to cancel, then the same cancellation policy would be applied. For example, if you have a strict policy, then even if you cancel, the guest would not be refunded for the first week (or whatever the specified period of time is for that policy).
Regarding holding the calendar hostage.... yeah that sucks but I don't get worked up over that part because it's more of an "inevitable cost of business" than blatant rule and policy violation by AirBnB administration.... like if you cancelled on someone who showed up with dogs, they should only be reimbursed for whichever part of their stay is beyond the timeframe outlined in the cancellation policy.
