@alphaUsers should not be demonetized for multiple posts because of 1 post. It's excessive & unfair. You should tell users exactly why they're being demonetized.
Plagiarism is taking credit for someone else's content. Posting links of YouTube videos alone, is not plagiarism.
I get rewarded because I directed users to the content which they found interesting, not the content itself.
I do not have to say in verbatim, that the content is not mine. It's common sense.
