Badmanthought makes a good point when he says it's hard to create original and new content nowadays. We see it in industries like music, movies, etc. It's the same crap with a little twist to it. But that doesn't justify stealing someone's work, putting a different title on it, and calling it a new and revolutionary coin/project.
When we are on the subject of plagiarism in whitepapers, project announcements, bounty threads, signature campaigns, etc., don't you ever get the feeling that so many of them sound the same? Especially the sections explaining the rules and posting requirements. Isn't that also some type of plagiarism and word spinning as well?
The rules originated from someone. A 2nd user made some changes and improved them, a 3rd and 4th copied from him, and so on. Now many of them look the same, just different numbers and maybe a few new requirements. I wonder who the original creator and first signature campaign manager was that made all of this?
Why would you complicate your life and answer these questions? If someone uses someone else's material, then he should put a link to it.
Further, it doesn't matter who was the first source of this content.
I saw white papers of projects that had many links on each page. There is nothing wrong or forbidden in this.
