considering you can only see when the articles are published, not written, I'd say you're trying too hard...

The author had all these massive articles all on fairly different topics ready to go... and then decided to pump 4 of them in a span of 4 days.

If it looks like a duck...

...then it is clearly AI?

It isn't impossible that it's AI, but assuming writing and publishing happen at the same time would also lead you to conclude that Anne Frank wrote from the afterlife.

[Ronsenshi]

Not clearly, but given the world we live in makes me highly suspicious that AI was involved to one degree or another.

Plenty of people out there are happy to let AI do most of the work while claiming it as their own.
