Yes, you are right , if the repeat buyers does not help and only one bad review can shut down the sales.. than I am convinced that Fiverr hsa F..ked up the Algorithm... more they recent had 2 webinar and I believe they also know that they have messed up...they were telling people to use ChatGPT for Gig Title and Gig Description..
I think the best is to have multiple sales channel... as Fiverr is more prone to be exploited by the buyers and Sellers has to suffer...
