This sounds like scare tactics and no one can bully you into doing what you want with your own property.
As long as your guests respect your house rules.
We only hear the bad stories on 'brainwashing ' TV . Most guests are amazing and respectful. Reviews are 1 safeguard as you can learn from other hosts about "dodgy" guests .
I've been hosting 100s of guests from all around the world and Australia for over 3 years now and probably only 1 couple would never be welcome in my home again.
All my hundreds of guests prefer Airbnb . Hotels /Accommodation continuously slander Airbnb due to competition.
Every guest has said they prefer Airbnb especially my overseas guests. Meet and stay with informative locals !!!
