If you read what I wrote, they are not copied and pasted.
There are a ton of bots that scrape the internet for news stories, change just a few little bits of the headline and story, and then post them as their own. The more sophisticated ones apparently use automated AI scripts to rewrite the stories differently from the original article.
You can often tell them by the way they will use random foreign letters like ö instead of o, or ş instead of s etc. in the headlines, in order to avoid being immediate flagged as a copy.
They just harvest clicks in order to generate ad revenue, if one website gets shut down, or just becomes unpopular due to people cottoning on, they just switch up to the next one.
Some of them do have a bit of human input. They will have the bots automatically generate a ton of AI slop, and flag up those that are gaining clicks the fastest. The human operator will then edit those articles to remove any obvious AI weirdness so that it doesn't lose traction.
If you click on one that has only recently been scraped and posted, you will often see a lot of disjointed nonsense in the article, as the AI has misinterpreted the original story.
The Opera browser news feed on my phone used to be heavily infected with this crap, which is how I ended up going down the rabbit hole to find where it was all coming from. It seems to have calmed down a lot recently.
