This is not a fancy thing to post but I thought it might be helpful for others to avoid what I have done.
To keep it short, I have finished an order with a client and he gave me 3.7 stars rating. When he came back again he said that he liked my work and wanted more. Then I told him:
If you like my work why you gave me that rating? That will affect my rating and I always get 5 stars except that one. He felt guilty and asked me to send a request so that he can change the review but I did not. Anyway, the second order did not go well and we ended up with the Customer Support. After they checked our messages, they gave me a warning because I told the buyer that his rating will affect me. When I asked them what was all that about they said:
“IT IS NOT ALLOWED TO TELL THE BUYER THAT HIS RATING WAS BAD AND MAKING HIM FEEL GUILTY TO GET 5 STARS”
That what happened, so don’t talk with buyers about the rating
