I'm not sure if that's LLMs. I long suspected people to copy popular Reddit posts/stories here to gain attention. I've searched for some and they don't all seem to be dumped here from other places, so it has to be something else. But so far I didn't use any LLM detector service to find out if people made them up on their own or used ChatGPT... We might want to do that to gain some more insight.

But it's very annoying. I've unsubscribed from asklemmy and several ither communities as well, because of this.
