If you have to grow in this platform,you have to be original and post quality content otherwise there is no scope for you.

What can we post to Steemit?
We can post anything in this platform such as videos,photos,motivational stories,blogs etc but condition is that it should be legal and should not violate the terms and conditions of steem.To make our post better we can take help from internet but legally that’s we should not forget to mention the source from where material has been taken.

source

what I understand by Proof of Brain concept

Blockchain rewards the posts which should be either our own or we should give citation or source to content that we use but it’s someone else’s work.

You can take material from online(internet)as well as offline(books)and use it to make your posts informative.But for this you need to work under some rules;whenever you use any content,doesn’t matter from where it has been taken,you have to mention it’s source or actual author.
If you use the content without giving credit to them,firstly it’s against our morals,secondly it’s punishable in some countries and more importantly not mentioning source is a plagiarism,which is totally untolerable on Steem.And if you’re doing it again and again,you’ll be from posting.And your pending rewards will be taken back..

Plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work.

"An apple a day keeps the doctor away" is a common English-language proverb that appeared in the 19th century, advocating for the consumption of apples, and by extension, "if one eats healthy foods, one will remain in good health and will not need to see the doctor often."
Copy pasted without alteration that’s why i have put it in quotation marks

Apples are a true superfood in my opinion. "Researchers have long been aware of the potential for apple consumption to support balanced populations of bacteria in our lower digestive tract."source

Above example has only one original sentence

So instead of being copy cats,try to create your own content which will be appreciated,and if use someone else’s work to make your post better mention it’s source. it makes your blog look professional and also prevents you from being accused of plagiarism.
