Hello Ana thanks for your input. As you read Airbnb had already agree with the guest to delete my review if I detailed anything about the situation. Even when trying to do a low rating they blocked the ratings on his account. I think is self explanatory on what to expect. The Host should be upset at Airbnb.
99% of the time I write guest a review and in 3 years I had to write few bad reviews to alert any future host and let me explain why I changed my view on this by sharing what Airbnb did to one of those past bad reviews I left:
There was a guest who rented a room in my shared home, who was naked, only underwear, no blanket on and door wide open so that me and family can see him. I approached him and told him he need it to close the door, this man was on his 40s. When I wrote a review about my uncomfortable experience by this guest manners and disrespect knowing a family live in this house, Airbnb deleted my review from his account.
I asked Airbnb why they had done that as it was a very important thing to know for future host and they could not give a good answer. This was something I was deeply concerned that I felt responsible to share, not like any other non sense bad reviews that aren't even helpful, but if Airbnb can delete this easily as per guest request why then Im wasting time doing this? I block them. If any host is upset at this, they should be upset at the company who does this type of things.
Several months later I went back to check this individual account to see if anyone else had review him the same way and to my surprise his account was gone. My though is that because Airbnb deleted my review another incident happened to other host and then they decided to take action.
My take is Airbnb is no so serious about this and instead of focusing on writing bad things on a review that might end up being deleted I have learn how to protect myself.
