But do you think if this was the case, during many years nobody would have complained on the forum until now? There are quite a few people on the forum who regularly use Best Change services.
I saw few threads against Best_Change in the past. If my memory is correct, I do not think the feedback manipulation never was in anyone's mind before. If they had the same feedback system where there are no negative were visible then it proves my argument of eyeballs on only the positive random rating numbers. I think our brain is designed not to pay attention in flat numbers.
0/20, 0/10, 0/50, 0/32, 0/87 if these are some feedback data presented on a table to quick look then you are lost on the numbers that are changing at the right but while you are lost on those numbers, you are not really paying attention on why in the left all are 0.
