I recently purchased a few gigs and some sellers delivered great results and others barely tried. Fiverr is asking to rate the gig but I can’t give thumbs up because result was crappy, but SOMETHING was delivered so I feed bad in giving thumbs down - I need a neutral rating and then I can explain briefly that the person did not try very hard.
Suggestion - don’t rate the seller, and even better - let them know why you haven’t done so.
It will be an incentive for the seller to do better next time (hopefully, at least), but it won’t delude other buyers into buying a sub-par service.
Just my fiverr cents.
