I got and delivered my first order after two months (more or less) being on Fiverr. Now I have some perplexities about reviews and images to add in my Portfolio. I mean my buyer seems disappeared without releasing any review about my work or adding the image preview I sent to him in my Portfolio…
It is the prerogative of a buyer as to whether they want to leave a review or not.
Sellers have posted on the forum that they got a warning because they asked for a review.
Best just to leave it and move on.
Suggest you read the Terms of Service at the bottom of the Fiverr main page for the rules as to how Fiverr works.
Everything is explained there in great detail.
