Hello @David4376
Welcome to CC
There's always grey areas in law and one should have the right to an appeal process.
Use keywords here in CC and you will find others in the same boat, may I suggest you send them a msg and network together and challenge the legalities of it all.
You may also like to go through listings in your area and msg them an enquiry to see if they wish to perhaps take a class action.
Sometimes you will recognize listings in your location & if you have time maybe go and door knock as they may appreciate the networking.
The basic research systems used is often flawed and based on a very small sample of people - those research practices need to be challenged as there's all manner of reasons people should have the basic right to rent for whatever length of time suits them.
All the best
