Nevertheless, I checked the white paper and, as someone could expect nowadays, it looks like yet another attempt to ride the coin wagon though maybe a better one than others.
A data-oriented approach to hosting news and the relationships creation though seem interesting and the concepts can probably be used on the web sans coins. The user-based adding/checking/verifying process can be said is used on ./, HN and similar sites, where people will comment out any issues on the posted the article. Duplication probably exists so older articles of interest can be posted again.

Spam your scam elsewhere.
It's not spam when a longtime user is linking to their work in a relevant context and hasn't been making a habit of it. The two cases are trivial to tell apart if you're willing to take a minute, and it has always been ok to for users to tell others about their work this way on HN—as long as they don't overdo it. Whether you like the project or not is a separate question. As for thoughtfulness, "spam your scam elsewhere" is basically leading with a punch in the nose.
