Greetings friend @juanmolina.

It's very important what you just said, "sophisticated plagiarism," I imagine you mean they're doing everything they can not be easily detected.

I personally have seen a lot of bad intentions as soon as posts with stolen information, have detected them and immediately delete the post.

I believe, it is our duty to keep Steemit free from plagiarism and abuse, even if this is a lot of work.

Thank you very much for your intervention, my friend.
