This is so embarassing doing this kind of plagiarism. Stealing from steemit itself and posting there is - like here said is the worst kind of it all. It would affect the credibility of the real creator.
It should brought into attention of newcomers in all cost. A strong mentality against plagiarism should grow with every new comer into steemit. I think awareness programmes with rewards for helping to find malpractices like these would be helpful too.
