I posted about a 60,000+ article ecosystem here - https://news.ycombinator.com/item?id=36304763
Not to pick on the commentator, but at least on HN comment used it as an incorrect reference. I found it because I was going to use it as a reference, but I fact checked it and it was wrong. But also found a second ecosystem that fact check it as correct... I haven't looking into that ecosystem yet.
Incorrect information is good for SEO, because it's unique content. GPT can do it well with prodding. It's a very different beast to Markov chain or translation spam
