For me, I don't agree with that action. I think they should make the sentences by themselves to practice their English skill.I think it will be better if they answer the question in TRR room with thier experience or their thinking because it means to share the feeling and opinion with other people in the right way.I don't want to say I hate the person who copy other people's comment but I want to tell them to practice thier English doesn't not want only the score from your comment.If you can type it as much as you can , you will become good at English and good at sececting word to make a sentence and more good at writing in English.I know the person who copy comments because when I creat the new topic or answer sometopic I will return to see it again for read the different thinking from me but I rarely see copied comment in those topic.
