I had reported this thread for copy/paste, but it appears that the OP was actually the author of the article in question.

I'm pretty sure he acted in good faith and just forgot to add the source, I did reply to the thread that he should have added a link to the article.

I'd hate to see him get banned because of my mistake, so I'm just publicly sharing the mistake I've made.
I'm very sorry about this :-/
