I am glad to know the links were useful and helped you with the review.
As for your question "why some hosts don´t write negative reviews..."
1- Writing negative reviews does not affect superhost status.
2- I do not see reataliation as a reason, because neither the host nor the guest can see the reviews before both having posting the reviews or when 14 days after check out has passed.
However, what I have said above does not explain all the other reasons why some hosts does not write a negative review when some guest deserve it.
Sometimes it is a mystery. The ones who complain about bad guests and does not write bad reviews should have their say here!
Maybe only them know why they do not! 🙂
