alt Hacker News> Such as, say, Jon Corbet (@corbet), of LWN, whose activity on HN shows a similar pattern and roughly equivalent frequency.
I took a look at the most recent comments from both accounts and they don't look similar to me in this respect.
I think there are two questions here though:
1. Was the violation egregious?
2. Did it deserve an immediate ban, or did they deserve a warning etc.?
Seems to me the answer to (1) is yes, but the answer to (2) I'm less sure about.
Jon's been around a while and some of the piss and vinegar of youth may have subsided. He does tend to show up with LWN comes up, whether as a topic of discussion (or more often) from submitted articles. That's his baliwick, and again, I don't fault him at all for it.
Our other friend here is a more recent participant to HN, at least under this handle. (I don't know that there are others, only what I can see from this one.)
