what if the not so good private review comes after 50 good ones? this is what i think happened to me, a particularly difficult client, with an orientation to conflict and misunderstandings, very rude and confusing with the revisions, so the option is to cancel, which also hurts the impressions, or try to give the best possible service given the situation. His public review was already a bit harsh, but immediately after his order was finished I stopped receiving new messages, it was almost day and night, so my take on it was that he left a bad private review (actually when I asked support they kinda confirmed). This is where I also think the system is not fair, seems like it's not making any averages, it just takes the bad and punish you for it.
