Simple. Visit topic #22285, throw your arguments in a post along with some links or screenshots, and we can get that changed and update their Wiki page. Do note that this is an artist with a backlog that is almost a decade long, has developed their own recognizable style, and has provided the CG art of several adult games with physical releases. So whatever your arguments are, they better be more substantial than simple "feels like AI" vibechecks.
Also, keep in mind that there are LoRA models out there that have specifically been trained to mimic this artist's style.
