Precisely, it "looks like" HR was involved. Can you say with certainty this person, hired in Jan. 2014, was involved? And can you say with certainty that this person could have prevented this? Again, unless you're a GitHub insider (are you?), the answer is no. At the moment, no one on HN knows anything. It's entirely possible this was an HR issue, but specifically calling for the HR person to be suspended or fired, given our collective total ignorance, is a spiteful and bizarre declaration directed at someone the original poster does not know. These are real people, and HN comments – particularly top comments – can influence decisions.
