Need a New System/ Filter to weed out fake buyers and consent both parties before giving a false/ negative review.
It will be helpful for all.
You have to aware of this kind of buyer.
Unfortunately no sellers will give a consent to post negative review even if it’s objective negative review from buyer side.
I meant before they publish the buyer’s review for a completed gig. Inform the seller before posting if they want to dispute it before making it public because people automatically believe the negative review is true and then you will get some copycats.
