this isn't AI at all. some random guy added AI to the Pixiv tags themselves, not the artist.

I don't see any signs of AI whatsoever.

The AI tag is being persistently added on Pixiv, no matter how many times it's removed. Strangely, none of the other Pixiv posts from the artist are being labelled as such, only this one. Maybe it's the flagger doing this? They didn't even bother to add the "ai-generated" tag here. They are also ignoring the child post.

If it helps, here is an early draft, from the artist's old Twitter account.
