How can I see buyers feedback massages or feedback rating?
I don’t think you can. Although I sure hope someone comes along behind me and says I’m wrong. One thing you can do though is do a Google Search of the buyers username specifically on Fiverr site.
For those who might not already know how to search one specific site on Google:
Precede your query with site:fiverr.com - So, for example if you were to search for me I would put this in the Google search bar: oranjegirl site:fiver.com
It won’t show you their rating as a buyer but if they have left negative feedback for other sellers you will generally find those in the results.
