Since the AI hate bandwagon started, people have been randomly accusing artists of being AI on social media without bothering to check their previous work or art style (this has even happened to long established anime artists that work for major studios, despite their style predating AI art), to get attention and virtue signal. And of course, nobody who joins in on the mass harassment bothers to check the artist's previous work or art style either, because they don't actually care if it's AI, they just wanted to harass someone in the safety of a group and feel good about it.
This is especially stupid because a mass majority of people who create AI art publicly do not in any way hide they used AI to generate the art, because they know people who look at their AI art do not care that it's AI generated.
And as AI improves it'll become almost impossible to actually tell it's AI generated based on art style alone.
