I have three "unhandled" reports against this user for plagiarism. The oldest one is from December 17th, and is for the post you have linked to. The most recent one is from today, and is for this post which is plagiarized from this CoinTelegraph article (from the word "secretly" onwards").

It's pretty obvious that this isn't a case of a "mistaken quote" or simply "forgetting to include the link", and he's trying to farm merit for his signature campaign. I'm not sure why he isn't being banned.
