Achievement 3 by @sergeyk Task : Content Etiquette

Hello..!!
I have passed achievements 1&2. And now I pass achievements3 - Content Etiquette "What is Plagiarism"

Plagiarism begins at school, when less intelligent or more lazy students write off homework in those who did it. But what kind of plagiarism is this? Everything happens with the consent of the author. Maybe so. But this leads to plagiarism - to show the teacher's homework as if done by himself.

From the very beginning, the Stimit platform has been promoting original content, fighting plagiarism, and now even groups have appeared looking for plagiarism on the platform.
It is possible that the diaries of the game were made to distract from plagiarism. Let them write better about their day than copy someone else's.
I have read about the original content and plagiarism here more than once. Plagiarism is direct - when you just copy someone else's work. Without any references to primary sources or even a mention of the author. But because of the fight against plagiarism, he "learned" to disguise himself. You can steal an idea, but present it in your own words. And you can just replace their words with other forms (synonyms) mosaic plagiarism.
But in doing so, I heard about Proof of Brain. I have not come across this before.

"Steem provides a scalable blockchain protocol1 for publicly accessible and immutable content, along with a fast and fee-less digital token (called STEEM)2 which enables people to earn the currency by using their brain (what can be called “Proof-of-Brain”)." ^sourse

I liked it, I heard about many different "Proof-of- .." and I hear about it for the first time.
It is often necessary to quote someone's work. This should be done correctly.
You need to re-quote, which is usually placed in quotation marks "quote" put the symbol ">" and then the platform sitmit will represent it accordingly.
Other people's material must be used with the consent of the author.
Sometimes works (pictures) with free access are published
I know such as https://shutterstock.com, https://pixabay.com/
Але беручи картинки звідти слід теж вказати джерело [sourse] (url)
