Ran into a "sports news" site which is almost certainly all AI-generated. All the articles -- dozens and dozens a day-- are credited to a male "NBA fan" who is a "dentist". If you look them up, it seems like they've stolen the name and approximate details of a female dentist. (female, not male name). And the articles are all re-swizzled versions of other published articles, i.e. the AI is plagiarizing articles at scale. Not unusual and unexpected nowadays, but annoying.
