Yeap, joining late to the conversation but this just happened to me.
I made a reservation 6 months prior my trip. 14 weeks after the host cancelled because I refused to paid a sum of 3 times more my initial price, stating that "there was an issue with the system".
Airbnb only gives a compensation of 10% of the initial price paid, and so far I have not received any help on relocating. I can not afford the prices now cus all that is left is 4 times more of what I paid.
Airbnb says the host gets penalized but the penalty is only $50/$100. I told them that's nothing compared to what the host is going to make for reenlisting the place at a higher price. I was told by Airbnb that the host gets the dates blocked to prevent booking on those days but I see is available to anyone who would like to book it.
So far what I have learn from all of this is that the customer get's little protection on this, since now the time has passed and I can not afford the prices that are left. and Airbnb gets more money out of it since the host can just post the listing again at a higher price and their cut from it is more than what they would've got with what I paid for mine.
