I agree with this somewhat, it doesn’t seem to make much sense to evaluate a gig like that right away, though for one this would be the buyer’s responsibility to not review a gig before knowing it really was done properly, and for another, fiverr would have to lengthen the time window for leaving reviews even more for such cases, which again wouldn’t be good for the many gigs that can easily be evaluated within the given time frame, I guess the time windows, like most other things, are compromises between buyers’ and sellers’ side they came up with.
And then you have to take into account that some reviews might be from return buyers. So while my gigs, translations, are anyway something you usually should be able to check within the given timeframe, I think it does sometimes happen that a return customer of mine leaves a review right away, I suppose because they know from experience that they are happy with my work and don’t want to log in again for a rating later so they just accept and right away rate the delivery all in one, and the rating includes things like communication too.
But again, that’s not because of my, the seller’s, doings, but by choice of the buyer, I don’t even ask for a rating at all since quite a while, so there’s certainly no pressure from me.
If buyers let sellers push them to rate before they even checked, in cases we’ve seen complaints about apparently even rated a gig the seller didn’t yet deliver fully, then that’s the fault of the buyer as well. Why let oneself be pushed.
That said, generally sellers of course shouldn’t try to tell their customers how to rate them. If a seller tried to do that with me it would definitely be the last time I purchased their service, and depending on how they tried to do it, might report it to Customer Service.
And you can find several mentions on fiverr’s pages that offering refunds for better rating and such aren’t okay. I’d recommend everyone, sellers and buyers to regularly read up on TOS and policies, there sometimes are updates and many don’t seem to ever read them at all from what one gets to read here on the forum.
