What is the use of writing in the comments of old posts - nobody reads them anyway! And only I will see new notifications about my posts. Your work will not be useful in this case. And you will not see new my posts without indicating the source (if it'll be required). So what is the point of your work ?? You only bother me because my posts are hidden by low rating. But the new posts are without plagiarism and all can see it! So what's the point? What benefit have you brought to society?
And for copy-paste comments you also get money
