I am talking about this post where the writer does not write anything himself. Just copy and paste a few paragraphs from the article and the link to the source, no effort done and creates a post that look like a quality post with zero effort.
If nothing was added to original text, and if that members is repeating this activity all the time, than I would make report for moderators and label it as low quality post.
Even if technically this is not really plagiarism, it is falling into same category and it's not adding any value to forum or conversation.
For such posts that are 100% using source words, text should be quoted, and maybe they should be posted in News section.
