Who are you or anyone to say or decide what is plagiarism or not and above all, take destructive actions against others? Apparently, you have not read the terms of service of the blockchain steemit. And if you have read them, it is infamous that you do not respect those terms and support those who do not respect them either.

Point number 7 of the terms of the Steemit service: "7. No Liability for Third-Party Services and Content

7.1. In using our Services, you may view content or use services provided by third parties, including links to web pages and services of such parties ("Third-Party Content"). We do not control, endorse, or adopt any Third-Party Content and will have no responsibility for Third-Party Content including, without limitation, material that may be misleading, incomplete, erroneous, offensive, indecent, or otherwise objectionable in your jurisdiction. In addition, your dealings or correspondence with such third parties are only between you and the third parties. We are not responsible or liable for any loss or damage of any sort incurred because of any such dealings and you understand that your use of Third-Party Content, and your interactions with third parties, is at your own risk. "

So don´t talk nonsense.
