It's pretty well established that this blog is LLM generated. The cpp subreddit has recently banned it, for example.
I don't think this is a fair assessment. Submissions from specific sources are more frequent in niche forums, as this helps them stand out. So once a blog is found to be spamming, it's easier to target the blog and not individual submissions.
This is much harder to do on generalist forums such as HN.
At this point, my only reason for still being around on here is because I simply don't know of any place that I find strictly better. Most of the popular alternatives to HN are annoying in ways that I find equally hard or even harder to tolerate.
