Though I didn't get banned, I had a similar experience with Airbnb recently.
Booked a hotel. When we got there, it was abandoned! Host unresponsive. Clearly a scam. Reported it to Airbnb, and after some back and forth we got our money back (pretty quickly tbf). We naturally left a bad review, warning others.
But then the host left us a bad review, despite never even meeting us or interacting with us in any way! We complained to Airbnb and of course, they "saw nothing that violates their review policy"... Diabolical.

I am sure that that listing is probably still up.
