There is another point that I would like to raise concerning private feedback.
It can be used intentionally to target and destroy someone's career on Fiverr, either by competitors or people who know the freelancer personally and wish him ill.
(Sadly, I think this is my case, as I think some family members are trying to manipulate the system. I am not bringing personal drama to the platform; I am merely stating how the system can be manipulated.)
I think Fiverr should not give first-time buyers, or buyers in general, too much power to destroy loyal freelancers who actually have better motives to build a career on the platform.
Feedback should be made public so that if a freelancer believes a bad rating is unfair, he or she can’t change it, but will be aware of it and will not continue to work with that client.
Truly, it makes no sense to give me a bad review, destroy my career, and keep coming back to me?
