You are welcome, @yateghteghs.
It's considered plagarism because you want to earn from it. Have you consider YouTube music videos that gets taken down? Even though you cite the singer as long as your purpose is to earn from it, it is considered plagiarism. If you have canceled reward on the post, then your point would have been valid.

Citing means, you copy someone's work just to make emphasis on your own point, and at the end make reference to the person. For instance when a person in a middle of his work says "Abraham Lincoln once said". Cited works normally don't take up to 25% of a your total work, some publishes insist on 20 for journals. But the "citation" rating of yours was almost 90, that's truly why it wasn't curated.

We learn everyday. You can still post an original work by you and be upvoted by EPISTEM. Thanks for understanding.
