There's obviosly more of the same topic in
https://news.ycombinator.com/submitted?id=atomashpolskiy , but just accepting "5 links in total to 3 different pieces of J. Corbett's investigation on BGMF." at face value, can you elaborate why do you think that posting five links in total about the same investigation is acceptable behavior?
To me, the first time is absolutely reasonable, repeating it a second time is a bit shady, but making the third, fourth and fifth posts are clearly crossing the line to spam, no matter what the topic is. If the community voted that it's not interested in the first two submissions, then that topic should be set aside, not resubmitted again and again.
