@Putin
Because the text of the postcard did not make much sense to me at first. Although it was not very polite, I registered it, hoping to communicate with the sender to understand what do the words mean. After the conversation, I understood that the person had written the postcard with malice. This user had no respect for me. So I want to block this user and lower the ranking.
That's what happened recently.
Thank you for your help! But the system noticed me that I should tell the sender why after uploading the photo I still give a low ranking. It seems I cannot change the ranking.
