Customer Reviews vs Buisness Owner Reviews. Do you enjoy writing reviews? Do you write bad reviews or Good Reviews?

How would it make you feel if a Buisness Owner wrote a bad review about you placing you on the black list of Customers? I was inspired to ask this question because in Italy now they have created on line platforms where Buisness Owners can write reviews on Customers especially bad ones. What are your thoughts concerning the topic?
