Horrid Airbnb Experience - Getting in touch with Airbnb

After our adventure with B., the recovering alcoholic, I decided to look through Airbnb for some cues on B.
The profile of B. appeared OK. the people on the page did not complain of any issue with him whatsoever. Only one person said that ''he could not stay anymore in their property'' - does that mean that he could stay because he wrecked the place? or because they had a change of plan?

Who knows.

B. has mental health issues. Am I the one who needs to make this personal matter public on a social media platform?  So I wrote '' B. cannot stay in my property anymore and I hope that he will find a group of people who will be able to support him''. Is it the appropriate language to use?

I contacted Airbnb to let them know about B. - they gave me a call and kind of told me that I need to be careful with the people I am bringing to my home. I told them, yes but there was no indication that this person was poorly. Furthermore, don't you have a policy against discrimination on the basis of someone health?

Airbnb is a fabulous tool for people to share their spaces with others and learn from them. Yet, we have to be prepared to deal with some of darker side of what it means to be a human.
